Description Kristian Fiskerstrand (RETIRED) gentoo-dev 2014-06-23 13:30:21 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.

qemu-2.1.0 is in the tree now.  i think we should wait the normal 30 day period.
