camlimages - arbitrary code execution

Tielei Wang discovered that CamlImages, an open source image processing
library, suffers from several integer overflows which may lead to a
potentially exploitable heap overflow and result in arbitrary code
execution.

For the old stable distribution (etch), this problem has been fixed in
version 2.20-8+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 2.2.0-4+lenny1.

For the unstable distribution (sid), this problem has been fixed in
version 3.0.1-2.

We recommend that you upgrade your camlimages package.
