Debian DSA-2650-2 : libvirt - files and device nodes ownership change to kvm group

low Nessus Plugin ID 65586

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Bastian Blank discovered that libvirtd, a daemon for management of virtual machines, network and storage, would change ownership of devices files so they would be owned by user 'libvirt-qemu' and group 'kvm', which is a general purpose group not specific to libvirt, allowing unintended write access to those devices and files for the kvm group members.

Solution

Upgrade the libvirt packages.

For the stable distribution (squeeze), this problem has been fixed in version 0.8.3-5+squeeze5.
