openSUSE Security Update: Security update for dbus-1, dbus-1-x11 ______________________________________________________________________________ Announcement ID: openSUSE-SU-2015:0300-1 Rating: moderate References: #916343 Cross-References: CVE-2015-0245 Affected Products: openSUSE 13.2 openSUSE 13.1 ______________________________________________________________________________ An update that fixes one vulnerability is now available. Description: dbus-1, dbus-1-x11 were updated to version 1.8.16 to fix one security issue. This update fixes the following security issue: - CVE-2015-0245: Do not allow non-uid-0 processes to send forged ActivationFailure messages. On Linux systems with systemd activation, this would allow a local denial of service (bnc#916343). These additional security hardenings are included: - Do not allow calls to UpdateActivationEnvironment from uids other than the uid of the dbus-daemon. If a system service installs unsafe security policy rules that allow arbitrary method calls (such as CVE-2014-8148) then this prevents memory consumption and possible privilege escalation via UpdateActivationEnvironment. - Do not allow calls to UpdateActivationEnvironment or the Stats interface on object paths other than /org/freedesktop/DBus. Some system services install unsafe security policy rules that allow arbitrary method calls to any destination, method and interface with a specified object path.
