Debian: DSA-2448-1 Urgent: Buffer Overflow in PDF Handling

Alexander Gavrun discovered an integer overflow in the TIFF library
in the parsing of the TileSize entry, which could result in the execution
of arbitrary code if a malformed image is opened.

For the stable distribution (squeeze), this problem has been fixed in
version 3.9.4-5+squeeze4.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your tiff packages.
