Detail
A security issue affects the following Ubuntu releases: Ubuntu 9.10 Ubuntu 10.04 LTS Ubuntu 10.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 9.10: Ubuntu 10.04 LTS: Ubuntu 10.10: In general, a standard system update will make all the necessary changes. Details follow: 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. |

Title: | DSA-2194-1 libvirt -- insufficient checks | ||
Description: | It was discovered that libvirt, a library for interfacing with different virtualization systems, did not properly check for read-only connections. This allowed a local attacker to perform a denial of service or possibly escalate privileges. The oldstable distribution is not affected by this problem. | ||
