Description Petr Matousek 2010-06-24 22:01:28 UTC
It was found that libvirt did not extract the defined disk backing store
format when recursing into disk image backing stores in the security
drivers. This could be possibly exploited by priviledged guest user to
access arbitrary files on the host.

This issue affects libvirt >= 0.7.2.
