Package        : gtksee
Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0444

Viliam Holub discovered a bug in gtksee whereby, when loading PNG
images of certain color depths, gtksee would overflow a heap-allocated
buffer.  This vulnerability could be exploited by an attacker using a
carefully constructed PNG image to execute arbitrary code when the
victim loads the file in gtksee.

For the stable distribution (woody) this problem has been fixed in
version 0.5.0-6.

For the unstable distribution (sid) this problem will be fixed soon.
Refer to Debian bug #76346.

We recommend that you update your gtksee package.

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.
