-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256
Quick Emulator(Qemu) built with the i8255x (PRO100) NIC emulation support is vulnerable to a memory leakage issue. It could occur while unplugging the device, and 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 on the host and/or potentially crash the Qemu process on the host. https://lists.gnu.org/archive/html/qemu-devel/2016-10/msg03024.html https://bugzilla.redhat.com/show_bug.cgi?id=1389538
