Background ========== D-Bus is a daemon providing a framework for applications to communicate with one another. GLib is a library providing a number of GNOME's core objects and functions. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/dbus < 1.6.8 >= 1.6.8 2 dev-libs/glib < 2.32.4-r1 >= 2.32.4-r1 ------------------------------------------------------------------- 2 affected packages Description =========== When libdbus is used in a setuid program, a user can gain escalated privileges by leveraging the DBUS_SYSTEM_BUS_ADDRESS variable. GLib can be used in a setuid context with D-Bus, and so can trigger this vulnerability. Please review the CVE identifier below for more details. Impact ====== A local attacker could gain escalated privileges and execute arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All D-Bus users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.6.8" All GLib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.32.4-r1" References ========== [ 1 ] CVE-2012-3524 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3524 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201406-01.xml 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.
