Multiple vulnerabilities have been found in GraphicsMagick, the image
processing system.

CVE-2018-20184

    The WriteTGAImage function (tga.c) is affected by a heap-based buffer
    overflow. Remote attackers might leverage this vulnerability to cause
    a denial of service via a crafted image file.

CVE-2018-20185

    The ReadBMPImage function (bmp.c) is affected by a heap-based buffer
    over-read. Remote attackers might leverage this vulnerability to cause
    a denial of service via a crafted image file.

CVE-2018-20189

    The ReadDIBImage function (coders/dib.c) is affected by an assertion
    error. Remote attackers might leverage this vulnerability to cause
    a denial of service via a crafted image file.

For Debian 8 "Jessie", these problems have been fixed in version
1.3.20-3+deb8u5.

We recommend that you upgrade your graphicsmagick packages.
