Description Marcus Meissner 2017-08-21 11:29:09 UTC
CVE-2017-12809

   Hello,

Quick emulator built with the IDE disk and CD/DVD-ROM Emulator support is 
vulnerable to a null pointer dereference issue. It could occur while flushing 
an empty CDROM device drive.

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

Upstream patch:
