| Description: | Summary:
The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2012:0153-1 advisory.
Vulnerability Insight:
The SUSE Linux Enterprise 11 SP1 kernel has been updated to 2.6.32.54, fixing numerous 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.
(CVE-2011-2699
> )
