libvirt-domain.c in libvirt supports virDomainGetTime API calls by guest agents with an RO connection, even though an RW connection was supposed to be required. This could lead to could lead to potentially disclosing unintended information or denial of service by causing libvirt to block.
For Debian 8 ‘Jessie’, this problem has been fixed in version 1.2.9-9+deb8u6.
We recommend that you upgrade your libvirt packages.
