Use-after-free / double-free problems were reported for QEMU's VNC server: https://bugzilla.redhat.com/show_bug.cgi?id=501131 https://bugzilla.redhat.com/show_bug.cgi?id=505641 Problem can cause QEMU process (and hence virtual machine) to crash (which is not security in most use cases, as VNC access means console access for the virtual machine), but if used for code execution, it can mean guest -> host escape. Versions in between the following two commits are affected: http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=753b405331 http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=198a0039c5 -- Tomas Hoger / Red Hat Security Response Team
