CVE-2011-4600

Name of the Vulnerable Software and Affected Versions libvirt versions prior to 0.9.9

Description The issue is related to the networkReloadIptablesRules function in libvirt, which does not properly handle firewall rules on bridge networks when libvirtd is restarted. This might allow remote attackers to bypass intended access restrictions via a DNS or DHCP query.

Recommendations For versions prior to 0.9.9, update to version 0.9.9 or later to resolve the issue. As a temporary workaround, consider restricting access to bridge networks to minimize the risk of exploitation.
