GNOME VFS is the GNOME virtual file system. It provides a modular architecture and ships with several modules that implement support for various local and remote file systems as well as numerous protocols, including HTTP, FTP, and others. A buffer overflow flaw was discovered in the GNOME virtual file system when handling data returned by CDDB servers. If a user connected to a malicious CDDB server, an attacker could use this flaw to execute arbitrary code on the victim"s machine. Users of gnome-vfs and gnome-vfs2 are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running GNOME sessions must be restarted for the update to take effect.
