USN-214-1: libungif vulnerabilities
===========================================================
Ubuntu Security Notice USN-214-1 November 07, 2005
libungif4 vulnerabilities
CVE-2005-2974, CVE-2005-3350
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 4.10 (Breezy Badger)
The following packages are affected:
libungif4g
The problem can be corrected by upgrading the affected package to
version 4.1.0b1-6ubuntu0.1 (for Ubuntu 4.10), 4.1.3-1ubuntu0.1 (for
Ubuntu 5.04), or 4.1.3-2ubuntu0.1 (for Ubuntu 5.10). In general, a
standard system upgrade is sufficient to effect the necessary changes.
Details follow:
Chris Evans discovered several buffer overflows in the libungif
library. By tricking an user (or automated system) into processing a
specially crafted GIF image, this could be exploited to execute
arbitrary code with the privileges of the application using libungif.
