Description:
=========================================================== Ubuntu Security Notice USN-640-1 September 03, 2008 libxml2 vulnerability CVE-2008-3281 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.04 Ubuntu 7.10 Ubuntu 8.04 LTS 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: libxml2 2.6.24.dfsg-1ubuntu1.2 Ubuntu 7.04: libxml2 2.6.27.dfsg-1ubuntu3.2 Ubuntu 7.10: libxml2 2.6.30.dfsg-2ubuntu1.2 Ubuntu 8.04 LTS: libxml2 2.6.31.dfsg-2ubuntu1.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Andreas Solberg discovered that libxml2 did not handle recursive entities safely. If an application linked against libxml2 were made to process a specially crafted XML document, a remote attacker could exhaust the system's CPU resources, leading to a denial of service.
