USN-1011-1 fixed a vulnerability in Firefox. This update provides the
corresponding update for Thunderbird.

Original advisory details:

Morten Krakvik discovered a heap-based buffer overflow in Firefox. If a
user were tricked into navigating to a malicious site, an attacker could
cause a denial of service or possibly execute arbitrary code as the user
invoking the program.

Update instructions

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

Ubuntu 9.10
Ubuntu 8.04
Ubuntu 10.10
Ubuntu 10.04

After a standard system update you need to restart Thunderbird to make all
the necessary changes.
