Debian: imlib arbitrary code execution fix
Posted by Joe Shakespeare   
Debian Pavel Kankovsky discovered that several overflows found in the libXpm library were also present in imlib, an imaging library for X and X11. An attacker could create a carefully crafted image 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.

Package        : imlib
Vulnerability  : buffer overflows, integer overflows
Problem-Type   : local/remote
Debian-specific: no
CVE ID         : CAN-2004-1025 CAN-2004-1026
BugTraq ID     : 11830
Debian Bug     : 284925

Pavel Kankovsky discovered that several overflows found in the libXpm
library were also present in imlib, an imaging library for X and X11.
An attacker could create a carefully crafted image 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 identifies the following
problems:

CAN-2004-1025

    Multiple heap-based buffer overflows.

CAN-2004-1026

    Multiple integer overflows.

For the stable distribution (woody) these problems have been fixed in
version 1.9.14-2woody2.

For the unstable distribution (sid) these problems have been fixed in
version 1.9.14-17.1.

We recommend that you upgrade your imlib packages immediately.


Upgrade Instructions
--------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
