The TIFFGetField function in coders/tiff.c in GraphicsMagick 1.3.24 allows remote attackers to cause a denial of service (out-of-bounds heap read) via a file containing an "unterminated" string.

Various security issues were discovered in Graphicsmagick, a collection of image processing tools. Heap-based buffer overflows or overreads may lead to a denial of service or disclosure of in-memory information or other unspecified impact by processing a malformed image file.

For Debian 8 'Jessie', these problems have been fixed in version 1.3.20-3+deb8u3.

We recommend that you upgrade your graphicsmagick packages.

A possible heap overflow was discovered in the EscapeParenthesis() function (CVE-2016-7447).

Various issues were found in the processing of SVG files in GraphicsMagick (CVE-2016-7446).

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).

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, causing a denial of service (CVE-2016-7448)

Various security issues were found and fixed in graphicsmagick in Debian wheezy LTS.

CVE-2016-7446

Heap buffer overflow issue in MVG/SVG rendering.

CVE-2016-7447

Heap overflow of the EscapeParenthesis() function

CVE-2016-7449

TIFF related problems due to use of strlcpy use.

CVE-2016-7800

Fix unsigned underflow leading to heap overflow when parsing 8BIM chunk.

For Debian 7 'Wheezy', these problems have been fixed in version 1.3.16-1.1+deb7u4.

We recommend that you upgrade your graphicsmagick packages.
