libcairo - arbitrary code execution

Peter Valchev (Google Security) discovered a series of integer
overflow weaknesses in Cairo, a vector graphics rendering library used
by many other applications. If an application uses cairo to render a
maliciously crafted PNG image, the vulnerability allows the execution
of arbitrary code.

For the stable distribution (etch), these problems have been fixed in
version 1.2.4-4.1+etch1.

For the unstable distribution (sid), these problems have been fixed in
version 1.4.10-1.1.

We recommend that you upgrade your libcairo packages.
