    products, allows remote attackers to cause a denial of service (stack-based buffer under-read) via a
    crafted bmp image. (CVE-2018-6876)

  - A stack-based buffer over-read in the ComputeResizeImage function in the MagickCore/accelerate.c file of
    ImageMagick 7.0.7-22 allows a remote attacker to cause a denial of service (application crash) via a
    maliciously crafted pict file. (CVE-2018-6930)

  - The ReadTIFFImage function in coders/tiff.c in ImageMagick 7.0.7-23 Q16 does not properly validate the
    amount of image data in a file, which allows remote attackers to cause a denial of service (memory
    allocation failure in the AcquireMagickMemory function in MagickCore/memory.c). (CVE-2018-7443)

    allows attackers to cause a denial of service (segmentation violation) via a crafted file. (CVE-2018-7470)

  - WriteEPTImage in coders/ept.c in ImageMagick 7.0.7-25 Q16 allows remote attackers to cause a denial of
    service (MagickCore/memory.c double free and application crash) or possibly have unspecified other impact
    via a crafted file. (CVE-2018-8804)

  - 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)

  - In ImageMagick 7.0.7-24 Q16, there is a heap-based buffer over-read in IsWEBPImageLossless in
    coders/webp.c. (CVE-2018-9135)
