Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.
