Debian: DSA-1835-1 Critical: TIFF Denial Of Service Risks

Several vulnerabilities have been discovered in the library for the
Tag Image File Format (TIFF). The Common Vulnerabilities and Exposures
project identifies the following problems:

CVE-2009-2285

It was discovered that malformed TIFF images can lead to a crash
in the decompression code, resulting in denial of service.

CVE-2009-2347

Andrea Barisani discovered several integer overflows, which
can lead to the execution of arbitrary code if malformed
images are passed to the rgb2ycbcr or tiff2rgba tools.

For the old stable distribution (etch), these problems have been fixed
in version 3.8.2-7+etch3.

For the stable distribution (lenny), these problems have been fixed in
version 3.8.2-11.2.

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

We recommend that you upgrade your tiff packages.
