Synopsis: Low: qemu-kvm security and bug fix update
Advisory ID: SLSA-2014:1669-2
Issue Date: 2014-10-20
CVE Numbers: CVE-2014-3615
--

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.
