CWE-284  (opens in a new tab)

How to fix?

Upgrade Echo:latest libvirt to version 0.9.9-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
