Synopsis:          Important: kernel security, bug fix, and enhancement update
Advisory ID:       SLSA-2013:1801-1
Issue Date:        2013-12-12
CVE Numbers:       CVE-2013-2141
                   CVE-2013-4470
                   CVE-2013-6367
                   CVE-2013-6368
--

* 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.
