CVE-2016-7448

The Utah RLE reader in GraphicsMagick before 1.3.25 allows remote attackers to cause a denial of service (CPU consumption or large memory allocations) via vectors involving the header information and the file size.

A possible heap overflow of the EscapeParenthesis() function (CVE-2016-7447).

The Utah RLE reader did not validate that header information was reasonable given the file size and so it could cause huge memory allocations and/or consume huge amounts of CPU (CVE-2016-7448).

The TIFF reader had a bug pertaining to use of TIFFGetField() when a 'count' value is returned. The bug caused a heap read overflow (due to using strlcpy() to copy a possibly unterminated string) which could allow an untrusted file to crash the software (CVE-2016-7449).

This update for GraphicsMagick fixes the following issues:

These vulnerabilities could be triggered by processing specially crafted image files, which could lead to a process crash or resource consumtion, or potentially have unspecified futher impact.
