Vulnerability Assessment Details

[DSA567] DSA-567-1 tiff

Vulnerability Assessment Summary
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.
