Debian DSA-2910-1 : qemu-kvm - security update

medium Nessus Plugin ID 73626
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Michael S. Tsirkin of Red Hat discovered a buffer overflow flaw in the way qemu processed MAC addresses table update requests from the guest.

A privileged guest user could use this flaw to corrupt qemu process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the qemu process.

Solution

Upgrade the qemu-kvm packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-5+squeeze11.

For the stable distribution (wheezy), this problem has been fixed in version 1.1.2+dfsg-6+deb7u1.
