ImageMagick version 7.0.7-28 contains a memory leak in WriteTIFFImage in coders/tiff.c.

This update for ImageMagick fixes the following issues:

These security issues were fixed:

• CVE-2017-13758: Prevent heap-based buffer overflow in the TracePoint() function (bsc#1056277).
• CVE-2017-10928: Prevent heap-based buffer over-read in the GetNextToken function that allowed remote attackers to obtain sensitive information from process memory or possibly have unspecified other impact via a crafted SVG document (bsc#1047356).
• CVE-2018-9133: Long compute times in the tiff decoder have been fixed (bsc#1087820).
• CVE-2018-11251: Heap-based buffer over-read in ReadSUNImage in coders/sun.c, which allows attackers to cause denial of service (bsc#1094237).
• CVE-2017-18271: Infinite loop in the function ReadMIFFImage in coders/miff.c, which allows attackers to cause a denial of service (bsc#1094204).
• CVE-2018-11655: Memory leak in the GetImagePixelCache in MagickCore/cache.c was fixed (bsc#1095730)
• CVE-2018-10804: Memory leak in WriteTIFFImage in coders/tiff.c was fixed (bsc#1095813)
• CVE-2018-10805: Fixed memory leaks in bgr.c, rgb.c, cmyk.c, gray.c, ycbcr.c (bsc#1095812)

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
