From ${URL} : Qemu emulator built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user/process could use this flaw to crash the Qemu instance, resulting in DoS issue. Upstream patch: - --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg02812.html Reference: - ---------- -> https://bugzilla.redhat.com/show_bug.cgi?id=1283934 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
This is fixed upstream: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=4c1396cb576c9b14425558b73de1584c7a9735d7
this is in qemu-2.5.0-r2 and is fine for stable
