The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5299 advisory.
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.
(CVE-2021-23215)
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR. This is a different flaw from CVE-2021-23215. (CVE-2021-26260)
There’s a flaw in OpenEXR’s ImfDeepScanLineInputFile functionality in versions prior to 3.0.5. An attacker who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The greatest risk from this flaw is to application availability. (CVE-2021-3598)
There’s a flaw in OpenEXR’s rleUncompress functionality in versions prior to 3.0.5. An attacker who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The greatest risk from this flaw is to application availability. (CVE-2021-3605)
An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits.
This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths. (CVE-2021-3933)
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;
and chroma.green.y * (X + Z))) / d;
but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR. (CVE-2021-3941)
OpenEXR 3.1.x before 3.1.4 has a heap-based buffer overflow in Imf_3_1::LineCompositeTask::execute (called from IlmThread_3_1::NullThreadPoolProvider::addTask and IlmThread_3_1::ThreadPool::addGlobalTask). NOTE:
db217f2 may be inapplicable. (CVE-2021-45942)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
