"An information leak flaw was found in the way QEMU's VGA emulator
accessed frame buffer memory for high resolution displays. A
privileged guest user could use this flaw to leak memory contents of
the host to the guest by setting the display to use a high resolution
in the guest. (CVE-2014-3615)

This update also fixes the following bug :

  - This update fixes a regression in the
    scsi_block_new_request() function, which caused all read
    requests to through SG_IO if the host cache was not
    used.

After installing this update, shut down all running virtual machines.
Once all virtual machines have shut down, start them again for this
update to take effect."
