Description Prasad Pandit 2014-04-15 18:13:27 UTC 
An out of bounds memory access flaw was found in Qemu's IDE device model.
It leads to Qemu's memory corruption via buffer overwrite(4 bytes). It occurs
while executing IDE SMART commands.

A privileged guest user could use this flaw to corrupt qemu process' memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the qemu process.
