Package : libpng3
Vulnerability : buffer overflows, 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) these problems have been fixed in version 1.2.1-1.1.woody.9.

For the unstable distribution (sid) these problems have been fixed in version 1.2.5.0-9.

We recommend that you upgrade your libpng3 packages.
