Description Agostino Sarubbo gentoo-dev 2017-04-26 08:02:26 UTC 
From ${URL} :

Quick Emulator(Qemu) built with the VMWARE PVSCSI paravirtual SCSI bus
emulation support is vulnerable to an infinite loop issue.
It could occur while initialising SCSI message ring buffer in pvscsi_log2().

A privileged user inside guest could use this flaw to consume host cpu cycles
or crash the Qemu process resulting in DoS.

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.
