According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
In ImageMagick 7.0.7-29 and earlier, a memory leak in the formatIPTCfromBuffer function in coders/meta.c was found. (CVE-2018-16750)
The ReadTIFFImage function in coders/tiff.c in ImageMagick 7.0.7-26 Q16 does not properly restrict memory allocation, leading to a heap-based buffer over-read. (CVE-2018-8960)
ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tiff file. (CVE-2018-9133)
The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-25665)
There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible during simple math calculations. This occurs in the rgb values and count
value for a color. The patch uses casts to ssize_t
type for these calculations, instead of int
. This flaw could impact application reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-25666)
TIFFGetProfiles() in /coders/tiff.c calls strstr() which causes a large out-of-bounds read when it searches for 'dc:format=\'image/dng\'
within profile
due to improper string handling, when a crafted input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to remedy this. This could cause an impact to availability of the application. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-25667)
WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to MagickMin() to ensure the proper value is used. This could impact application availability when a specially crafted input file is processed by ImageMagick. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-25674)
In the CropImage() and CropImageToTiles() routines of MagickCore/transform.c, rounding calculations performed on unconstrained pixel offsets was causing undefined behavior in the form of integer overflow and out-of-range values as reported by UndefinedBehaviorSanitizer. Such issues could cause a negative impact to application availability or other problems related to undefined behavior, in cases where ImageMagick processes untrusted input data. The upstream patch introduces functionality to constrain the pixel offsets and prevent these issues. This flaw affects ImageMagick versions prior to 7.0.9-0.
(CVE-2020-25675)
In CatromWeights(), MeshInterpolate(), InterpolatePixelChannel(), InterpolatePixelChannels(), and InterpolatePixelInfo(), which are all functions in /MagickCore/pixel.c, there were multiple unconstrained pixel offset calculations which were being used with the floor() function. These calculations produced undefined behavior in the form of out-of-range and integer overflows, as identified by UndefinedBehaviorSanitizer. These instances of undefined behavior could be triggered by an attacker who is able to supply a crafted input file to be processed by ImageMagick. These issues could impact application availability or potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-25676)
A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char
and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27750)
A flaw was found in ImageMagick in MagickCore/quantum-export.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long long
as well as a shift exponent that is too large for 64-bit type. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27751)
There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values, which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact to application availability or cause a denial of service. It was originally reported that the issues were in AcquireMagickMemory()
because that is where LeakSanitizer detected the leaks, but the patch resolves issues in the MIFF coder, which incorrectly handles data being passed to AcquireMagickMemory()
. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27753)
In IntensityCompare() of /magick/quantize.c, there are calls to PixelPacketIntensity() which could return overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the patch introduces and uses the ConstrainPixelIntensity() function, which forces the pixel intensities to be within the proper bounds in the event of an overflow. This flaw affects ImageMagick versions prior to 6.9.10-69 and 7.0.8-69. (CVE-2020-27754)
in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because the code which checks for the proper image depth size does not reset the size in the event there is an invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to application reliability, such as denial of service. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27755)
In ParseMetaGeometry() of MagickCore/geometry.c, image height and width calculations can lead to divide- by-zero conditions which also lead to undefined behavior. This flaw can be triggered by a crafted input file processed by ImageMagick and could impact application availability. The patch uses multiplication in addition to the function PerceptibleReciprocal()
in order to prevent such divide-by-zero conditions.
This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27756)
A floating point math calculation in ScaleAnyToQuantum() of /MagickCore/quantum-private.h could lead to undefined behavior in the form of a value outside the range of type unsigned long long. The flaw could be triggered by a crafted input file under certain conditions when it is processed by ImageMagick. Red Hat Product Security marked this as Low because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27757)
A flaw was found in ImageMagick in coders/txt.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long long
. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27758)
In IntensityCompare() of /MagickCore/quantize.c, a double value was being casted to int and returned, which in some cases caused a value outside the range of type int
to be returned. The flaw could be triggered by a crafted input file under certain conditions when processed by ImageMagick. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27759)
In GammaImage()
of /MagickCore/enhance.c, depending on the gamma
value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. The patch uses the PerceptibleReciprocal()
to prevent the divide-by- zero from occurring. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68.
(CVE-2020-27760)
WritePALMImage() in /coders/palm.c used size_t casts in several areas of a calculation which could lead to values outside the range of representable type unsigned long
undefined behavior when a crafted input file was processed by ImageMagick. The patch casts to ssize_t
instead to avoid this issue. Red Hat Product Security marked the Severity as Low because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to ImageMagick 7.0.9-0. (CVE-2020-27761)
A flaw was found in ImageMagick in coders/hdr.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char
. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68. (CVE-2020-27762)
A flaw was found in ImageMagick in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27763)
In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator() where a size_t cast should have been a ssize_t cast, which causes out-of-range values under some circumstances when a crafted input file is processed by ImageMagick. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to 6.9.10-69. (CVE-2020-27764)
A flaw was found in ImageMagick in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27765)
A flaw was found in ImageMagick in MagickCore/quantum.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of types float
and unsigned char
. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27767)
In ImageMagick, there is an outside the range of representable values of type ‘unsigned int’ at MagickCore/quantum-private.h. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27768)
In ImageMagick versions before 7.0.9-0, there are outside the range of representable values of type ‘float’ at MagickCore/quantize.c. (CVE-2020-27769)
Due to a missing check for 0 value of replace_extent
, it is possible for offset p
to overflow in SubstituteString(), causing potential impact to application availability. This could be triggered by a crafted input file that is processed by ImageMagick. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27770)
In RestoreMSCWarning() of /coders/pdf.c there are several areas where calls to GetPixelIndex() could result in values outside the range of representable for the unsigned char type. The patch casts the return value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was demonstrated in this case. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27771)

ImageMagick versions prior to 7.0.9-0. (CVE-2020-25676)
- A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker
who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form
of values outside the range of type `unsigned char` and math division by zero. This would most likely lead
to an impact to application availability, but could potentially cause other problems related to undefined
behavior. This flaw affects ImageMagick versions prior to 7.0.8-68. (CVE-2020-27750)
- A flaw was found in ImageMagick in MagickCore/quantum-export.c. An attacker who submits a crafted file
that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range
of type `unsigned long long` as well as a shift exponent that is too large for 64-bit type. This would
most likely lead to an impact to application availability, but could potentially cause other problems
related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27751)
- There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values,
which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact
to application availability or cause a denial of service. It was originally reported that the issues were
in `AcquireMagickMemory()` because that is where LeakSanitizer detected the leaks, but the patch resolves
issues in the MIFF coder, which incorrectly handles data being passed to `AcquireMagickMemory()`. This
flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27753)
- In IntensityCompare() of /magick/quantize.c, there are calls to PixelPacketIntensity() which could return
overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the
patch introduces and uses the ConstrainPixelIntensity() function, which forces the pixel intensities to be
within the proper bounds in the event of an overflow. This flaw affects ImageMagick versions prior to
6.9.10-69 and 7.0.8-69. (CVE-2020-27754)
- in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because
the code which checks for the proper image depth size does not reset the size in the event there is an
invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak
can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to

versions prior to 7.0.8-68. (CVE-2020-27759)
- In `GammaImage()` of /MagickCore/enhance.c, depending on the `gamma` value, it's possible to trigger a
divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an
impact to application availability. The patch uses the `PerceptibleReciprocal()` to prevent the divide-by-
zero from occurring. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68.
(CVE-2020-27760)
- WritePALMImage() in /coders/palm.c used size_t casts in several areas of a calculation which could lead to
values outside the range of representable type `unsigned long` undefined behavior when a crafted input
file was processed by ImageMagick. The patch casts to `ssize_t` instead to avoid this issue. Red Hat
Product Security marked the Severity as Low because although it could potentially lead to an impact to

`float` and `unsigned char`. This would most likely lead to an impact to application availability, but
could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick
versions prior to 7.0.9-0. (CVE-2020-27767)
- In ImageMagick, there is an outside the range of representable values of type 'unsigned int' at
MagickCore/quantum-private.h. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27768)
- In ImageMagick versions before 7.0.9-0, there are outside the range of representable values of type
'float' at MagickCore/quantize.c. (CVE-2020-27769)
- Due to a missing check for 0 value of `replace_extent`, it is possible for offset `p` to overflow in
SubstituteString(), causing potential impact to application availability. This could be triggered by a
crafted input file that is processed by ImageMagick. This flaw affects ImageMagick versions prior to
7.0.8-68. (CVE-2020-27770)
- In RestoreMSCWarning() of /coders/pdf.c there are several areas where calls to GetPixelIndex() could
result in values outside the range of representable for the unsigned char type. The patch casts the return
value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered
when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity
because although it could potentially lead to an impact to application availability, no specific impact
was demonstrated in this case. This flaw affects ImageMagick versions prior to 7.0.9-0. (CVE-2020-27771)
- A flaw was found in ImageMagick in coders/bmp.c. An attacker who submits a crafted file that is processed
by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned
int`. This would most likely lead to an impact to application availability, but could potentially cause
other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
(CVE-2020-27772)
- A flaw was found in ImageMagick in MagickCore/gem-private.h. An attacker who submits a crafted file that
is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of
type `unsigned char` or division by zero. This would most likely lead to an impact to application
availability, but could potentially cause other problems related to undefined behavior. This flaw affects
ImageMagick versions prior to 7.0.9-0. (CVE-2020-27773)
- A flaw was found in ImageMagick in MagickCore/quantum.h. An attacker who submits a crafted file that is
processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type
unsigned char. This would most likely lead to an impact to application availability, but could potentially
cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to
7.0.9-0. (CVE-2020-27775)
- A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is
processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type
unsigned long. This would most likely lead to an impact to application availability, but could potentially
cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to
7.0.9-0. (CVE-2020-27776)
- A flaw was found in ImageMagick in coders/jp2.c. An attacker who submits a crafted file that is processed
by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest threat
from this vulnerability is to system availability. (CVE-2021-20241)
- A flaw was found in ImageMagick in MagickCore/resize.c. An attacker who submits a crafted file that is
processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The
highest threat from this vulnerability is to system availability. (CVE-2021-20243)
- A flaw was found in ImageMagick in MagickCore/visual-effects.c. An attacker who submits a crafted file
that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero.
The highest threat from this vulnerability is to system availability. (CVE-2021-20244)
- A flaw was found in ImageMagick in MagickCore/resample.c. An attacker who submits a crafted file that is
processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The
highest threat from this vulnerability is to system availability. (CVE-2021-20246)
