Ubuntu Security Notice USN-1094-1
29th March, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 9.10
An attacker could send crafted input to libvirt and cause it to crash.
- libvirt - Libvirt virtualization toolkit
Petr Matousek discovered that libvirt did not always honor read-only
connections. An attacker who is authorized to connect to the libvirt daemon
could exploit this to cause a denial of service via application crash.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 10.10:
- libvirt0 0.8.3-1ubuntu14.1
- Ubuntu 10.04 LTS:
- libvirt0 0.7.5-5ubuntu27.9
- Ubuntu 9.10:
- libvirt0 0.7.0-1ubuntu13.3
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.
