  Red Hat Security Advisory 2012-0302-03

   » ‎ Packet Storm Security Advisories
  Red Hat Security Advisory 2012-0302-03 - The Common UNIX Printing System provides a portable printing layer for Linux, UNIX, and similar operating systems. A heap-based buffer overflow flaw was found in the Lempel-Ziv-Welch decompression algorithm implementation used by the CUPS GIF image format reader. An attacker could create a malicious GIF image file that, when printed, could possibly cause CUPS to crash or, potentially, execute arbitrary code with the privileges of the "lp" user.

  Mandriva Linux Security Advisory 2011-152

   » ‎ Packet Storm Security Advisories
  Mandriva Linux Security Advisory 2011-152 - An integer underflow leading to array index error was found in the way gzip used to decompress files / archives, compressed with the Lempel-Ziv-Welch compression algorithm. A remote attacker could provide a specially-crafted LZW compressed gzip archive, which once decompressed by a local, unsuspecting user would lead to gzip crash, or, potentially to arbitrary code execution with the privileges of the user running gzip. The updated packages have been upgraded to the 4.2.4.4 version which is not vulnerable to this issue.

  FreeBSD-SA-10-08.bzip2.txt

   » ‎ Packet Storm Security Recent Files
  FreeBSD Security Advisory - The bzip2/bunzip2 utilities and the libbz2 library compress and decompress files using an algorithm based on the Burrows-Wheeler transform. They are generally slower than Lempel-Ziv compressors such as gzip, but usually provide a greater compression ratio. When decompressing data, the run-length encoded values are not adequately sanity-checked, allowing for an integer overflow.

  USN-889-1.txt

   » ‎ Packet Storm Security Recent Files
  Ubuntu Security Notice 889-1 - It was discovered that gzip incorrectly handled certain malformed compressed files. If a user or automated system were tricked into opening a specially crafted gzip file, an attacker could cause gzip to crash or possibly execute arbitrary code with the privileges of the user invoking the program. Aki Helin discovered that gzip incorrectly handled certain malformed files compressed with the Lempel–Ziv–Welch (LZW) algorithm. If a user or automated system were tricked into opening a specially crafted gzip file, an attacker could cause gzip to crash or possibly execute arbitrary code with the privileges of the user invoking the program.
