SuSE 11.3 Security Update : Linux kernel (SAT Patch Numbers 8524 / 8525 / 8528)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.

Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to
version 3.0.101 and also includes various other bug and security

The following features have been added :

- Drivers: hv: Support handling multiple VMBUS versions

fixed :

- 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). (CVE-2013-2206)
