Description Agostino Sarubbo gentoo-dev 2017-02-07 07:57:56 UTC
From ${URL} :

Quick Emulator(Qemu) built with the CCID Card device emulator support
is vulnerable to an integer overflow flaw. It could occur while passing
message via command/responses packets to and from the host.

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