GLib is a library providing a number of GNOME’s core objects and functions. </p> </background> <description> <p>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. </p> </description> <impact type="high"> <p>A local attacker could gain escalated privileges and execute arbitrary code. </p> </impact> <workaround> <p>There is no known workaround at this time.</p> </workaround> <resolution> <p>All D-Bus users should upgrade to the latest version:</p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.6.8" </code> <p>All GLib users should upgrade to the latest version:</p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.32.4-r1" </code> </resolution> <references> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3524">CVE-2012-3524</uri> </references> <metadata tag="requester" timestamp="2012-10-14T18:04:56Z">ackle</metadata> <metadata tag="submitter" timestamp="2014-06-01T14:05:31Z"> creffett </metadata> </glsa>
