Scientific Linux Security Update : xen on SL5.x i386/x86_64 (Venom)

High Nessus Plugin ID 83460

Synopsis

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

Description

An out-of-bounds memory access flaw was found in the way QEMU's virtual Floppy Disk Controller (FDC) handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest. (CVE-2015-3456)

After installing the updated packages, all running fully-virtualized guests must be restarted for this update to take effect.

Solution

Update the affected packages.
