Description Agostino Sarubbo gentoo-dev 2016-01-29 08:14:40 UTC
From ${URL} :

Qemu emulator built with an IDE AHCI emulation support is vulnerable to a null 
pointer dereference flaw. It occurs while unmapping the Frame Information 
Structure(FIS) & Command List Block(CLB) entries.

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