DSA 628-1: New imlib2 packages fix arbitrary code execution

New imlib2 packages are available for Debian GNU/Linux

Debian Security Advisory DSA 628-1 security@debian.org

---------------------------------------------------------------------------

Package : imlib2
Vulnerability : integer overflows
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2004-1026

Pavel Kankovsky discovered that several overflows found in the libXpm library were also present in imlib and imlib2, imaging libraries for X11. An attacker could create a carefully crafted image file in such a way that it could cause an application linked with imlib or imlib2 to execute arbitrary code when the file was opened by a victim. The Common Vulnerabilities and Exposures project identifies the following problems:

CAN-2004-1025

Multiple heap-based buffer overflows. No such code is present in imlib2.

CAN-2004-1026

Multiple integer overflows in the imlib library.

For the stable distribution (woody) these problems have been fixed in version 1.0.5-2woody2.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your imlib2 packages.

Upgrade Instructions
