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.
