Package : libtiff
Date : December 3, 2009
Affected: 2008.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in libtiff:

Buffer underflow in the LZWDecodeCompat function in libtiff 3.8.2
allows context-dependent attackers to cause a denial of service (crash)
via a crafted TIFF image, a different vulnerability than CVE-2008-2327
(CVE-2009-2285).

Fix several places in tiff2rgba and rgb2ycbcr that were being careless
about possible integer overflow in calculation of buffer sizes
(CVE-2009-2347).

This update provides fixes for these vulnerabilities.

Update:

Packages for 2008.0 are being provided due to extended support for
Corporate products.
