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

medium Nessus Plugin ID 62949

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the tiff packages.

For the stable distribution (squeeze), this problem has been fixed in version 3.9.4-5+squeeze7.
