=========================================================== Ubuntu Security Notice USN-889-1 January 20, 2010 gzip vulnerabilities CVE-2009-2624, CVE-2010-0001 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 8.04 LTS Ubuntu 8.10 Ubuntu 9.04 Ubuntu 9.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: gzip 1.3.5-12ubuntu0.3 Ubuntu 8.04 LTS: gzip 1.3.12-3.2ubuntu0.1 Ubuntu 8.10: gzip 1.3.12-6ubuntu2.8.10.1 Ubuntu 9.04: gzip 1.3.12-6ubuntu2.9.04.1 Ubuntu 9.10: gzip 1.3.12-8ubuntu1.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: 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. (CVE-2009-2624) 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.
