Description Prasad Pandit 2017-02-06 19:28:41 UTC 
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.
