openSUSE Security Update : dbus-1 / dbus-1-x11 (openSUSE-2015-150)
High Nessus Plugin ID 81397
SynopsisThe remote openSUSE host is missing a security update.
Descriptiondbus-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.
SolutionUpdate the affected dbus-1 / dbus-1-x11 packages.
