Description Prasad J Pandit 2017-01-17 19:10:43 UTC
Quick Emulator(Qemu) built with the ac97 audio device emulation support is
vulnerable to a memory leakage issue. It could occur while doing a device
unplug operation; Doing so repeatedly would result in leaking host memory,
affecting other services on the host.

A privileged user inside guest could use this flaw to cause a DoS and/or
potentially crash the Qemu process on the host.
