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.
