SuSE 11.1 Security Update : Linux kernel (SAT Patch Number 5732)

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

The SUSE Linux Enterprise 11 SP1 kernel was updated to 2.6.32.54,
fixing lots of bugs and security issues.

The following security issues have been fixed :

- A potential hypervisor escape by issuing SG_IO commands
to partitiondevices was fixed by restricting access to
these commands. (CVE-2011-4127)

- KEYS: Fix a NULL pointer deref in the user-defined key
type, which allowed local attackers to Oops the kernel.
(CVE-2011-4110)

- Avoid potential NULL pointer deref in ghash, which
allowed local attackers to Oops the kernel.
(CVE-2011-4081)

- Fixed a memory corruption possibility in xfs readlink,
which could be used by local attackers to crash the
system or potentially execute code by mounting a
prepared xfs filesystem image. (CVE-2011-4077)

- A overflow in the xfs acl handling was fixed that could
be used by local attackers to crash the system or
potentially execute code by mounting a prepared xfs
filesystem image. (CVE-2012-0038)

- A flaw in the ext3/ext4 filesystem allowed a local
attacker to crash the kernel by getting a prepared
ext3/ext4 filesystem mounted. (CVE-2011-4132)

- Access to the taskstats /proc file was restricted to
avoid local attackers gaining knowledge of IO of other
users (and so effecting side-channel attacks for e.g.
guessing passwords by typing speed). (CVE-2011-2494)

- When using X.25 communication a malicious sender could
corrupt data structures, causing crashes or potential
code execution. Please note that X.25 needs to be setup
to make this effective, which these days is usually not
the case. (CVE-2010-3873)

- When using X.25 communication a malicious sender could
make the machine leak memory, causing crashes. Please
note that X.25 needs to be setup to make this effective,
which these days is usually not the case.
(CVE-2010-4164)

- A remote denial of service due to a NULL pointer
dereference by using IPv6 fragments was fixed. The
following non-security issues have been fixed:.
