DSA-567-1 tiff Detailed Explanation for this Vulnerability Assessment Several problems have been discovered in libtiff, the Tag Image File Format library for processing TIFF graphics files. A possible hacker could prepare a specially crafted TIFF graphic that would cause the client to execute arbitrary code or crash. The Common Vulnerabilities and Exposures Project has identified the following problems: Chris Evans discovered several problems in the RLE (run length encoding) decoders that could lead to arbitrary code execution. Matthias Clasen discovered a division by zero through an integer overflow. Dmitry V. Levin discovered several integer overflows that caused malloc issues which can result to either plain crash or memory corruption. For the stable distribution (woody) these problems have been fixed in version 3.5.5-6woody1. For the unstable distribution (sid) these problems have been fixed in version 3.6.1-2. We recommend that you upgrade your libtiff package.
