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.

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

Ubuntu 9.10

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