Authentication Bypass

libvirt is vulnerable to authentication bypass. When the password on a VNC server is set to an empty string, improper disabling of password checking allows remote attackers to bypass authentication and establish a VNC session by connecting to the server. The affected component is Password Checker...

Information Disclosure

libvirt is vulnerable to information disclosure. It was discovered that the virDomainSnapshotGetXMLDesc and virDomainSaveImageGetXMLDesc functions did not sufficiently limit the usage of the VIRDOMAINXMLSECURE flag when fine-grained ACLs were enabled. A remote attacker able to establish a...
