Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization Hypervisor through the 3.2 Manager administration portal, the Host may appear with the status of "Install Failed". If this happens, place the host into maintenance mode, then activate it again to get the host back to an "Up" state A stack-based buffer overflow flaw was found in the way the reds_handle_ticket() function in the spice-server library handled decryption of ticket data provided by the client. A remote attacker able to initiate a SPICE connection to the guest could use this flaw to crash the guest. (CVE-2013-4282) This issue was discovered by Tomas Jamrisko of Red Hat.
