  Hello,

An out-of-bounds heap buffer access issue was found in the way iSCSI Block 
driver in QEMU handled response coming from an iSCSI server, while checking 
status of a Logical Address Block (LBA) in iscsi_co_block_status() routine.

A remote user could use this flaw to crash the QEMU process resulting in DoS 
OR potentially execute arbitrary code with privileges of the QEMU process on 
the host.

Upstream patch:
---------------

This issue was reported by Felipe Franciosi, Raphael Norwitz and Peter 
Turschmid of nutanix.com.

Thank you.
