Description Prasad J Pandit 2017-04-28 09:22:24 UTC
Quick Emulator(Qemu) built with the Audio subsystem support is vulnerable to
a host memory leakage issue. It could occur if a guest user was to repeatedly
start and stop audio capture.

A privileged user inside guest could use this flaw to exhaust host memory,
resulting in DoS.
