28th July, 2011
A security issue affects these releases of Ubuntu and its derivatives:

Eric Blake discovered an integer overflow flaw in libvirt. A remote
authenticated attacker could exploit this by sending a crafted VCPU RPC
call and cause a denial of service via application crash.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.04:
- libvirt-bin 0.8.8-1ubuntu6.5
- Ubuntu 10.10:
- libvirt-bin 0.8.3-1ubuntu19.1
- Ubuntu 10.04 LTS:
- libvirt-bin 0.7.5-5ubuntu27.16
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
