CVE-2017-5579
First published: Tue Jan 24 2017(Updated: )
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.
