Background ========= GnomeVFS is a filesystem abstraction library for the GNOME desktop environment. libcdaudio is a multi-platform CD player development library. They both include code to query CDDB servers to get Audio CD track titles. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 gnome-base/gnome-vfs < 2.8.4-r1 > = 2.8.4-r1 2 media-libs/libcdaudio < 0.99.10-r1 > = 0.99.10-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description ========== Joseph VanAndel has discovered a buffer overflow in Grip when processing large CDDB results (see GLSA 200503-21). The same overflow is present in GnomeVFS and libcdaudio code. Impact ===== A malicious CDDB server could causeapplications making use of GnomeVFS or libcdaudio libraries to crash, potentially allowing the execution of arbitrary code with the privileges of the user running the application. Workaround ========= There is no known workaround at this time. Resolution ========= All GnomeVFS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =gnome-base/gnome-vfs-2.8.4-r1" All libcdaudio users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =media-libs/libcdaudio-0.99.10-r1" References ========= [ 1 ] CAN-2005-0706 https://www.cve.org/CVERecord?id=CVE-CAN-2005-0706 [ 2 ] GLSA 200503-21 https://security.gentoo.org/glsa/200503-21 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200504-07 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
