Description Agostino Sarubbo gentoo-dev 2016-10-25 07:49:11 UTC
From ${URL} :

Quick Emulator(Qemu) built with the RTL8139 ethernet controller emulation
support is vulnerable to an infinite loop issue. It could occur while
transmitting packets in C+ mode of operation.

A privileged user inside guest could use this flaw to consume excessive CPU
cycles on the host, resulting in DoS situation.

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.
