"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.

to automatically clean and format it as much as possible without
introducing additional issues.");
