Description Agostino Sarubbo gentoo-dev 2016-12-06 16:14:33 UTC 
From ${URL} :

Quick Emulator(Qemu) built with the USB redirector usb-guest support is 
vulnerable to a memory leakage flaw. It could occur while destroying the USB 
redirector in 'usbredir_handle_destroy'.

A guest user/process could use this issue to leak host memory, resulting in 
DoS for a host.

@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.
Comment 1 SpanKY gentoo-dev 2016-12-29 18:52:39 UTC 
this is in the 2.8.0 release
Comment 2 Thomas Deutschmann (RETIRED) gentoo-dev 2017-01-01 18:56:22 UTC 
@ Maintainer(s): Can we start stabilization of =app-emulation/qemu-2.8.0?
Comment 3 SpanKY gentoo-dev 2017-01-02 17:55:55 UTC 
(In reply to Thomas Deutschmann from comment #2)

give it like two weeks and we can move forward if there are no reported bugs
Comment 4 Thomas Deutschmann (RETIRED) gentoo-dev 2017-01-21 10:57:45 UTC 
More than two weeks later, no new bugs (only bugs regarding unneeded deps which are now resolved), so let's start stabilization.


@ Arches,

please test and mark stable: =app-emulation/qemu-2.8.0
