Security Advisory Description

Description

The dbus-daemon in D-Bus before 1.6.24 and 1.8.x before 1.8.8 does not properly close old connections, which allows local users to cause a denial of service (incomplete connection consumption and prevention of new connections) via a large number of incomplete connections. (CVE-2014-3639)

Impact

A local user may be able to run an application to exploit D-Bus and cause a disruption of service.

Note: As of February 17, 2015, AskF5 Security Advisory articles include the Severity value. Security Advisory articles published before this date do not list a Severity value.

Recommended Action

If the previous table lists a version in the Versions known to be not vulnerable column, you can eliminate this vulnerability by upgrading to the listed version. If the listed version is older than the version you are currently running, or if the table does not list any version in the column, then no upgrade candidate currently exists.

F5 responds to vulnerabilities in accordance with the Severity values published in the previous table. The Severity values and other security vulnerability parameters are defined in K4602: Overview of the F5 security vulnerability response policy.

To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict command line access for affected systems to trusted users. For more information, refer to K13309: Restricting access to the Configuration utility by source IP address (11.x) and K13092: Overview of securing access to the BIG-IP system.
