Debian DSA 571-1 Critical: Libpng Buffer Overflow Issues

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.
