Debian DSA-3161-1 : dbus - security update

low Nessus Plugin ID 81302

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Simon McVittie discovered a local denial of service flaw in dbus, an asynchronous inter-process communication system. On systems with systemd-style service activation, dbus-daemon does not prevent forged ActivationFailure messages from non-root processes. A malicious local user could use this flaw to trick dbus-daemon into thinking that systemd failed to activate a system service, resulting in an error reply back to the requester.

Solution

Upgrade the dbus packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.6.8-1+deb7u6.
