SuSE 11.2 Security Update : Linux kernel (SAT Patch Numbers 7123 / 7127)

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 SP2 kernel has been updated to 3.0.51
which fixes various bugs and security issues.

It contains the following feature enhancements :

- The cachefiles framework is now supported (FATE#312793,
bnc#782369). The userland utilities were published
seperately to support this feature.

- The ipset netfilter modules are now supported
(FATE#313309) The ipset userland utility will be
published seperately to support this feature.

- The tipc kernel module is now externally supported

- Hyper-V KVP IP injection was implemented (FATE#314441).
A seperate hyper-v package will be published to support
this feature.

- Intel Lynx Point PCH chipset support was added.

- Enable various md/raid10 and DASD enhancements.
(FATE#311379) These make it possible for RAID10 to cope
with DASD devices being slow for various reasons - the
affected device will be temporarily removed from the

Also added support for reshaping of RAID10 arrays.

mdadm changes will be published to support this feature.

The following security issues have been fixed :

- A race condition on hot adding memory could be used by
local attackers to crash the system during hot adding
new memory. (CVE-2012-5517)

- A flaw has been found in the way Linux kernels KVM
subsystem handled vcpu->arch.cr4 X86_CR4_OSXSAVE bit set
upon guest enter. On hosts without the XSAVE feature and
using qemu userspace an unprivileged local user could
have used this flaw to crash the system. (CVE-2012-4461)

- The KVM implementation in the Linux kernel allowed host
OS users to cause a denial of service (NULL pointer
dereference and host OS crash) by making a
KVM_CREATE_IRQCHIP ioctl call after a virtual CPU
already exists. (CVE-2012-1601)

- Attempting an rds connection from the IP address of an
IPoIB interface to itself causes a kernel panic due to a
BUG_ON() being triggered. Making the test less strict
allows rds-ping to work without crashing the machine. A
local unprivileged user could use this flaw to crash the
sytem. (CVE-2012-2372)

- Dimitry Monakhov, one of the ext4 developers, has
discovered a race involving asynchronous I/O and
fallocate which can lead to the exposure of stale data
--- that is, an extent which should have had the
'uninitialized' bit set indicating that its blocks have
not yet been written and thus contain data from a
deleted file will get exposed to anyone with read access
to the file. (CVE-2012-4508)

- The rds_recvmsg function in net/rds/recv.c in the Linux
kernel did not initialize a certain structure member,
which allows local users to obtain potentially sensitive
information from kernel stack memory via a (1) recvfrom
or (2) recvmsg system call on an RDS socket.

- The sfc (aka Solarflare Solarstorm) driver in the Linux
kernel allowed remote attackers to cause a denial of
service (DMA descriptor consumption and
network-controller outage) via crafted TCP packets that
trigger a small MSS value. (CVE-2012-3412)
