Ubuntu Security Notice USN-25-1		  November 15, 2004
libgd2 vulnerability
CAN-2004-0941
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libgd2-noxpm
libgd2-xpm

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

Details follow:

CAN-2004-0990 described several more buffer overflows which had been
discovered in libgd2's PNG handling functions. However, it was
determined that the update from USN-11-1 was not sufficient to prevent
every possible attack, so another update is required.

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.
