December 17, 2012
A security issue affects these releases of Ubuntu and its derivatives:
Summary:
Aptdaemon could be tricked into installing arbitrary PPA GPG keys.
Software Description:
Details:
It was discovered that Aptdaemon incorrectly validated PPA GPG keys when
importing from a keyserver. If a remote attacker were able to perform a
man-in-the-middle attack, this flaw could be exploited to install altered
package repository GPG keys.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
aptdaemon 0.43+bzr805-0ubuntu7
Ubuntu 11.10:
aptdaemon 0.43+bzr697-0ubuntu1.3
After a standard system update you need to reboot your computer to make
all the necessary changes.
