RHSA-2004:465 - Security Advisory

Topic

An updated imlib package that fixes several heap overflows is now available.

Description

Imlib is an image loading and rendering library.

Several heap overflow flaws were found in the imlib BMP image handler. An
attacker could create a carefully crafted BMP file in such a way that it
could cause an application linked with imlib to execute arbitrary code when
the file was opened by a victim. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-0817 to this issue.

Users of imlib should update to this updated package which contains
backported patches and is not vulnerable to this issue.
