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.

Comment 2 Petr Matousek 2010-07-12 11:31:10 UTC

This issue affects libvirt >= 0.7.2.

Comment 3 Petr Matousek 2010-07-12 12:13:15 UTC

Statement:

Not vulnerable. This issue did not affect the version of libvirt as shipped with Red Hat Enterprise Linux 5.
