Descriptions
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.
La función networkReloadIptablesRules en network/bridge_driver.c en libvirt en versiones anteriores a 0.9.9 no maneja correctamente las reglas del firewall en redes puente cuando se reinicia libvirtd, lo que podría permitir a atacantes remotos eludir las restricciones de acceso previstas a través de una consulta (1) DNS o (2) DHCP.
It was discovered that libvirt incorrectly handled the firewall rules on bridge networks when the daemon was restarted. This could result in an unintended firewall configuration. This issue only applied to Ubuntu 12.04 LTS. Peter Krempa discovered that libvirt incorrectly handled locking when certain ACL checks failed. A local attacker could use this issue to cause libvirt to stop responding, resulting in a denial of service. This issue only applied to Ubuntu 14.04 LTS. Various other issues were also addressed.
