Affected Products:
SUSE Linux Enterprise Real Time 11 SP2
______________________________________________________________________________

An update that solves one vulnerability and has 42 fixes is
now available. It includes one version update.

Description:


The SUSE Linux Enterprise 11 Service Pack 2 kernel for
RealTime was updated to version 3.0.101 and also includes
various other bug and security fixes.

The following features have been added:

* Drivers: hv: Support handling multiple VMBUS versions
(FATE#314665).
* Drivers: hv: Save and export negotiated vmbus version
(FATE#314665).
* Drivers: hv: Move vmbus version definitions to
hyperv.h (FATE#314665).

The following security issue has been fixed:

* CVE-2013-2206: The sctp_sf_do_5_2_4_dupcook function
in net/sctp/sm_statefuns.c in the SCTP implementation in
the Linux kernel did not properly handle associations
during the processing of a duplicate COOKIE ECHO chunk,
which allowed remote attackers to cause a denial of service
(NULL pointer dereference and system crash) or possibly
have unspecified other impact via crafted SCTP traffic.
(bnc#826102)

The following non-security bugs have been fixed:

* mm: Do not walk all of system memory during show_mem

over its own threads.

its mm.

during scan.

remapping (bnc#844513).
* iommu: Remove stack trace from broken irq remapping
warning (bnc#844513).
