27 April 2009

acpid vulnerability




It was discovered that acpid did not properly handle a large number of
connections. A local user could exploit this and monopolize CPU resources,
leading to a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04
Ubuntu 8.10
Ubuntu 8.04
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
