libgd2 - integer overflows

“infamous41md” discovered several integer overflows in the PNG image
decoding routines of the GD graphics library. This could lead to the
execution of arbitrary code on the victim’s machine.

For the stable distribution (woody) these problems have been fixed in
version 1.8.4-17.woody3 of libgd1 and in version 2.0.1-10woody1 of
libgd2.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your libgd2 packages.
