DLA-541-1 libvirt -- LTS security update

Date Reported:
01 Jul 2016
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2016-5008.
More information:

It was discovered that there was a password policy issue in libvirt, a library for interfacing with different virtualization systems.

Setting an empty graphics password is documented as a way to disable VNC/SPICE access, but QEMU does not always behave like that. VNC would happily accept the empty password. We enforce the behavior by setting password expiration to now.

For Debian 7 Wheezy, this issue has been fixed in libvirt version

We recommend that you upgrade your libvirt packages.
