Package        : libpng
Vulnerability  : integer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0955

Several integer overflows have been discovered by its upstream
developers in libpng, a commonly used library to display PNG graphics.
They could be exploited to cause arbitrary code to be executed when a
specially crafted PNG image is processed.

For the stable distribution (woody) this problem has been fixed in
version 1.0.12-3.woody.9.

For the unstable distribution (sid) this problem has been fixed in
version 1.0.15-8.

We recommend that you upgrade your libpng packages.
