Detailsinfo

A vulnerability, which was classified as critical, was found in Freedesktop Dbus-glib up to 0.100. This affects the function dbus_g_proxy_manager_filter. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The dbus_g_proxy_manager_filter function in dbus-gproxy in Dbus-glib before 0.100.1 does not properly verify the sender of NameOwnerChanged signals, which allows local users to gain privileges via a spoofed signal.

The weakness was disclosed 03/05/2013 by Sebastian Krahmer as confirmed git commit (GIT Repository). It is possible to read the advisory at cgit.freedesktop.org. This vulnerability is uniquely identified as CVE-2013-0292 since 12/06/2012. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed by Sebastian Krahmer in ANSI C and been published 2 years after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 68765 (Oracle Linux 5 / 6 : dbus-glib (ELSA-2013-0568)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120965 (Red Hat Update for dbus-glib (RHSA-2013:0568)).
