=========================================================== Ubuntu Security Notice USN-315-1 July 12, 2006 libmms, xine-lib vulnerabilities =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 5.04 Ubuntu 5.10 Ubuntu 6.06 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 5.04: libxine1 1.0-1ubuntu3.8 Ubuntu 5.10: libmms0 0.1-0ubuntu1.2 libxine1c2 1.0.1-1ubuntu10.4 Ubuntu 6.06 LTS: libxine-main1 1.1.1+ubuntu2-7.2 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Matthias Hopf discovered several buffer overflows in libmms. By tricking a user into opening a specially crafted remote multimedia stream with an application using libmms, a remote attacker could exploit this to execute arbitrary code with the user's privileges. The Xine library contains an embedded copy of libmms, and thus needs the same security update.
