Background
libvirt is a library that provides a common API for managing various virtualization technologies. It allows applications to interact with different hypervisors, such as QEMU, KVM, and Xen, to create and manage virtual machines. This vulnerability affects libvirt version 0.9.12.3-1+deb7u2 in Debian 7 Wheezy.
Vulnerability Detail
The vulnerability in libvirt involves a password policy issue. While setting an empty graphics password is intended to disable VNC/SPICE access, QEMU does not always behave as expected. In some cases, VNC would still accept the empty password. To enforce the desired behavior, the password expiration is set to now. This ensures that the empty password is no longer accepted.
