Description Agostino Sarubbo gentoo-dev

From ${URL} :

Qemu emulator built with the e1000 NIC emulation support is vulnerable to an 
infinite loop issue. It could occur while processing data via transmit or 
receive descriptors, provided the initial receive/transmit descriptor 
head(TDH/RDH) is set outside the allocated descriptor buffer.

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