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

High Nessus Plugin ID 86894


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


A heap buffer overflow flaw was found in the way QEMU's NE2000 NIC emulation implementation handled certain packets received over the network. A privileged user inside a guest could use this flaw to crash the QEMU instance (denial of service) or potentially execute arbitrary code on the host. (CVE-2015-5279)

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


Update the affected packages.
