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. Affected: 2008.0
