Scientific Linux Security Update : kernel on SL6.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

This update fixes the following security issues :

- A flaw was found in the way KVM (Kernel-based Virtual
Machine) initialized a guest's registered pv_eoi
(paravirtualized end-of-interrupt) indication flag when
entering the guest. An unprivileged guest user could
potentially use this flaw to crash the host.
(CVE-2013-1935, Important)

- A missing sanity check was found in the
kvm_set_memory_region() function in KVM, allowing a
user-space process to register memory regions pointing
to the kernel address space. A local, unprivileged user
could use this flaw to escalate their privileges.
(CVE-2013-1943, Important)

- A double free flaw was found in the Linux kernel's
Virtual Ethernet Tunnel driver (veth). A remote attacker
could possibly use this flaw to crash a target system.
(CVE-2013-2017, Moderate)

The system must be rebooted for this update to take effect.
