Description Johannes Segitz 2014-06-23 15:37:56 UTC 
Qemu PCIe bus support is vulnerable to a use-after-free flaw. It could occur
via guest, when it tries to hotplug/hotunplug devices on the guest.

A user able to add & delete Virtio block devices on a guest could use this
flaw to crash the Qemu instance resulting in DoS.

-----------------

Couldn't figure out which versions are actually affected. Since RHEL6 isn't affected (0.12.1.2) we only need to worry about SLE 12 and openSUSE
