=========================================================== Ubuntu Security Notice USN-196-1 October 10, 2005 xine-lib vulnerability CAN-2005-2967 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) The following packages are affected: libxine1 The problem can be corrected by upgrading the affected package to version 1-rc5-1ubuntu2.3 (for Ubuntu 4.10), or 1.0-1ubuntu3.1.1 (for Ubuntu 5.04). In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Ulf Harnhammar discovered a format string vulnerability in the CDDB module's cache file handling in the Xine library, which is used by packages such as xine-ui, totem-xine, and gxine. By tricking an user into playing a particular audio CD which has a specially-crafted CDDB entry, a remote attacker could exploit this vulnerability to execute arbitrary code with the privileges of the user running the application. Since CDDB servers usually allow anybody to add and modify information, this exploit does not even require a particular CDDB server to be selected.
