It was discovered that libvirt incorrectly checked privileges when the virConnectDomainXMLToNative API function was used. An attacker could possibly use this flaw to gain write privileges, contrary to expected behaviour.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
