"This update for ImageMagick fixes the following issues: The following
security vulnerabilities were fixed :

  - CVE-2018-11625: Fixed heap-based buffer over-read in
    SetGrayscaleImage in the quantize.c file, which allowed
    remote attackers to cause buffer over-read via a crafted
    file. (bsc#1096200)

  - CVE-2018-11624: Fixed a use-after-free issue in the
    ReadMATImage function in coders/mat.c. (bsc#1096203)

  - CVE-2018-10805: Fixed several memory leaks in bgr.c,
    rgb.c, cmyk.c, gray.c, and ycbcr.c (bsc#1095812)

  - CVE-2018-12600: The ReadDIBImage and WriteDIBImage
    functions allowed attackers to cause an out of bounds
    write via a crafted file (bsc#1098545).

  - CVE-2018-12599: The ReadBMPImage and WriteBMPImage
    fucntions allowed attackers to cause an out of bounds
    write via a crafted file (bsc#1098546). The following
    other changes were made :

  - Fix -gamma issues in special cases. (bsc#1094745,
    bsc#1094742)
