Description Agostino Sarubbo gentoo-dev 2015-09-05 11:55:57 UTC
From ${URL} :

Qemu emulator built with the e1000 NIC emulation support is vulnerable to an
infinite loop issue. It could occur while processing transmit descriptor data
when sending a network packet.

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

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.
Comment 1 SpanKY gentoo-dev 2015-09-07 05:51:08 UTC
added fix sent upstream:

should be fine to stabilize (in addition to qemu-guest-agent)
