libpng - integer overflow

Jueri Aedla discovered an integer overflow in the libpng PNG library,
which could lead to the execution of arbitrary code if a malformed
image is processed.

For the stable distribution (squeeze), this problem has been fixed in
version 1.2.44-1+squeeze2.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your libpng packages.
