libvirt: CVE-2011-4600

Severity: Medium · CVSS 5.9CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N
Published: Dec 9, 2011, 12:00:00 AM UTC

EPSS: 1.78% · Oct 27, 2026

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.
