Debian Security Advisory DSA-2575-1 security@debian.org
http://www.debian.org/security/ Nico Golde
November 18, 2012 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : tiff
Vulnerability : heap-based buffer overflow
Problem type : local (remote)
Debian-specific: no
CVE ID : CVE-2012-4564
It was discovered that ppm2tiff of the tiff tools, a set of utilities
for TIFF manipulation and conversion, is not properly checking the return
value of an internal function used in order to detect integer overflows.
As a consequence, ppm2tiff suffers of a heap-based buffer overflow.
This allows attacker to potentially execute arbitrary code via a crafted
ppm image, especially in scenarios in which images are automatically
processed.
For the stable distribution (squeeze), this problem has been fixed in
version 3.9.4-5+squeeze7.
For the testing distribution (wheezy), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in
version 4.0.2-5.
We recommend that you upgrade your tiff packages.
