Debian DLA-1315-1 : libvirt security update

high Nessus Plugin ID 108605

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Daniel P. Berrange and Peter Krempa of Red Hat discovered a flaw in libvirt, a virtualization API. A lack of restriction for the amount of data read by QEMU Monitor socket can lead to a denial of service by exhaustion of memory resources.

For Debian 7 'Wheezy', these problems have been fixed in version 0.9.12.3-1+deb7u3.

We recommend that you upgrade your libvirt packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
