SUSE SLED12 / SLES12 Security Update : dbus-1 (SUSE-SU-2015:0457-1)

high Nessus Plugin ID 83693

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

dbus-1 was 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.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
