Description Prasad J Pandit 2017-01-24 17:50:12 UTC
Quick Emulator(Qemu) built with the 16550A UART serial 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.
