Debian DSA-2194-1 : libvirt - insufficient checks

medium Nessus Plugin ID 52718

Language:

Synopsis

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

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 (crash) or possibly escalate privileges.

The oldstable distribution (lenny) is not affected by this problem.

Solution

Upgrade the libvirt packages.

For the stable distribution (squeeze), this problem has been fixed in version 0.8.3-5+squeeze1.
