DSA-2575-1 tiff -- heap-based buffer overflow

Date Reported:
18 Nov 2012
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2012-4564.
More information:

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.
