Details
David Black discovered that Software Properties incorrectly validated
server certificates when performing secure connections to download PPA GPG
key fingerprints. If a remote attacker were able to perform a
machine-in-the-middle attack, this flaw could be exploited to install altered
package repository GPG keys.

The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.10

In general, a standard system update will make all the necessary changes.
