Description Agostino Sarubbo gentoo-dev 2015-08-10 10:28:27 UTC
From ${URL} :

It was reported that Qemu emulator built with the virtio-serial vmchannel support is vulnerable to a buffer overflow issue. It could occur while exchanging virtio control messages between guest & the host.

A malicious guest could use this flaw to corrupt few bytes of Qemu memory area, potentially crashing the Qemu process.

Upstream fix:

@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.
