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 :

* A flaw was found in the way the Linux kernel's TCP/IP protocol suite
implementation handled sending of certain UDP packets over sockets
that used the UDP_CORK option when the UDP Fragmentation Offload (UFO)
feature was enabled on the output device. A local, unprivileged user
could use this flaw to cause a denial of service or, potentially,
escalate their privileges on the system. (CVE-2013-4470, Important)

* A divide-by-zero flaw was found in the apic_get_tmcct() function in
KVM's Local Advanced Programmable Interrupt Controller (LAPIC)
implementation. A privileged guest user could use this flaw to crash
the host. (CVE-2013-6367, Important)

* A memory corruption flaw was discovered in the way KVM handled
virtual APIC accesses that crossed a page boundary. A local,
unprivileged user could use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2013-6368,
Important)

* An information leak flaw in the Linux kernel could allow a local,
unprivileged user to leak kernel memory to user space. (CVE-2013-2141,
Low)

This update also fixes several bugs and adds two enhancements.

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