Red Hat libvirt, possibly 0.6.1 through 0.8.2, looks up disk backing stores
without referring to the user-defined main disk format, which might allow
guest OS users to read arbitrary files on the host OS, and possibly have
unspecified other impact, via unknown vectors.

Notes

Author Note
jdstrand AppArmor 10.04 should mostly protect the host OS, but an attacker in a virtual machine may be able to access files of another machine. upstream patch is highly intrusive, needs rewriting for all affected releases, requires a conffile change and a migration helper. Ubuntu 10.04 LTS is the first release to probe the backing stores
