Description Agostino Sarubbo gentoo-dev 2015-12-09 10:54:18 UTC 
From ${URL} :

Qemu emulator built with the VNC display driver support is vulnerable to an 
arithmetic exception flaw. It occurs on the VNC server side while processing 
the 'SetPixleFormat' messages from a client.

A privileged remote client could use this flaw to crash the guest resulting in 
DoS.
