Bug 567868 – <app-emulation/qemu-2.5.0-r1: net: vmxnet3: host memory leakage (CVE-2015-{8567,8568})

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Agostino Sarubbo 2015-12-09 16:46:19 UTC]

From ${URL} :

Qemu emulator built with a VMWARE VMXNET3 paravirtual NIC emulator support is
vulnerable to a memory leakage flaw. It occurs when a guest repeatedly tries
to activate the vmxnet3 device.

A privileged guest user could use this flaw to leak host memory, resulting
in DoS on the host.

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.
