mono - buffer overflow

An integer overflow in the BigInteger data type implementation has been
discovered in the free .NET runtime Mono.

The oldstable distribution (sarge) doesn’t contain mono.

For the stable distribution (etch) this problem has been fixed in
version 1.2.2.1-1etch1. A powerpc build will be provided later.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your mono packages.
