"This update for ImageMagick fixes several issues. These security
issues were fixed :

  - CVE-2017-11534: Processing a crafted file in convert
    could have lead to a Memory Leak in the lite_font_map()
    function in coders/wmf.c (bsc#1050135).

  - CVE-2017-13133: The load_level function in coders/xcf.c
    lacked offset validation, which allowed attackers to
    cause a denial of service (load_tile memory exhaustion)
    via a crafted file (bsc#1055219).

  - CVE-2017-13139: The ReadOneMNGImage function in
    coders/png.c had an out-of-bounds read with the MNG CLIP
    chunk (bsc#1055430).

  - CVE-2017-15033: Fixed a memory leak in ReadYUVImage in
    coders/yuv.c (bsc#1061873).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
