Subject: [USN-11-1] libgd2 vulnerabilities

===========================================================
Ubuntu Security Notice USN-11-1            October 28, 2004
libgd2 vulnerabilities
CAN-2004-0990
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libgd2-xpm
libgd2-noxpm

The problem can be corrected by upgrading the affected packages to
version 2.0.23-2ubuntu0.1. In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Several buffer overflows have been discovered in libgd's PNG handling
functions.

If an attacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's privileges.
