Details

Florian Weimer discovered that the Module::Signature perl module
incorrectly loaded unknown ciphers from relative directories. An attacker
could possibly use this flaw to execute arbitrary code when a signature is
verified.

Update instructions

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

Ubuntu 13.04
Ubuntu 12.10
Ubuntu 12.04

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