========================================================================== Ubuntu Security Notice USN-1176-1 July 26, 2011
A security issue affects these releases of Ubuntu and its derivatives:
DBus could be made to crash if it processed a specially crafted message.
Software Description: - dbus: simple interprocess messaging system
It was discovered that DBus did not properly validate the byte order of messages under certain circumstances. An attacker could exploit this to cause a denial of service via application crash or potentially obtain access to sensitive information.
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.04: dbus 1.4.6-1ubuntu6.1
Ubuntu 10.10: dbus 1.4.0-0ubuntu1.3
Ubuntu 10.04 LTS: dbus 1.2.16-2ubuntu4.3
Ubuntu 8.04 LTS: dbus 1.1.20-1ubuntu3.5
After a standard system update you need to reboot your computer to make all the necessary changes.
