A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
The following packages are affected:
The problem can be corrected by upgrading the affected package to
version 1.1.0-12ubuntu2.1. In general, a standard system upgrade is
sufficient to effect the necessary changes.
Recently, Pavel Kankovsky discovered several buffer overflows in imlib
which were fixed in USN-53-1. It was found that imlib2 was vulnerable
to similar issues.
If an attacker tricked a user into loading a malicious XPM or BMP
image, he could exploit this to execute arbitrary code in the context
of the user opening the image.
These vulnerabilities might also lead to privilege escalation if a
privileged server process is using this library; for example, a PHP
script on the web server which does automatic image processing might
use the php-imlib package, in which case a remote attacker could
possibly execute arbitrary code with the web server's privileges.
