libgd1 - integer overflow

More potential integer overflows have been found in the GD graphics
library which weren’t covered by our security advisory
DSA 589. They
could be exploited by a specially crafted graphic and 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.woody4.

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

We recommend that you upgrade your libgd1 packages.
