Description Agostino Sarubbo gentoo-dev 2017-02-23 11:51:03 UTC
From ${URL} :

Quick Emulator(Qemu) built with the VNC display driver support is vulnerable
to an out-of-bounds memory access issue. It could occur while refreshing
the vnc display surface area in 'vnc_refresh_server_surface'.

A user/process inside guest could use this flaw to crash the Qemu process
resulting in DoS.

Older versions of Qemu are affected, latest upstream releases are not.

Upstream patch:


@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.

Older versions of Qemu are affected, latest upstream releases are not.


These are patches from 2012 and 2014 respectively. No ebuild since mid 2015 is affected.
