CVE-2011-4600  (opens in a new tab)
CWE-284  (opens in a new tab)

How to fix?

Upgrade libvirt to version 0.9.9 or higher.

Overview

Affected versions of this package are vulnerable to Improper Access Control. The networkReloadIptablesRules function in network/bridge_driver.c in libvirt before 0.9.9 does not properly handle firewall rules on bridge networks when libvirtd is restarted, which might allow remote attackers to bypass intended access restrictions via a (1) DNS or (2) DHCP query.
