Beschreibung:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory. Vulnerability Insight: The kernel packages contain the Linux kernel, the core of any Linux operating system. * A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AEC-GCM mode IPSec security association. (CVE-2015-3331, Important) This update also fixes the following bugs: * Previously, the kernel audit subsystem did not correctly track file path names which could lead to empty, or '(null)' path names in the PATH audit records. This update fixes the bug by correctly tracking file path names and displaying the names in the audit PATH records. (BZ#1197746) * Due to a change in the internal representation of field types, AUDIT_LOGINUID set to -1 (4294967295) by the audit API was asymmetrically converted to an AUDIT_LOGINUID_SET field with a value of 0, unrecognized by an older audit API. To fix this bug, the kernel takes note about the way the rule has been formulated and reports the rule in the originally given form. As a result, older versions of audit provide a report as expected, in the AUDIT_LOGINUID field type form, whereas the newer versions can migrate to the new AUDIT_LOGINUID_SET filed type. (BZ#1197748) * The GFS2 file system 'Splice Read' operation, which is used for the sendfile() function, was not properly allocating a required multi-block reservation structure in memory. Consequently, when the GFS2 block allocator was called to assign blocks of data, it attempted to dereference the structure, which resulted in a kernel panic. With this update, 'Splice read' operation properly allocates the necessary reservation structure in memory prior to calling the block allocator, and sendfile() thus works properly for GFS2. (BZ#1201256) * Moving an Open vSwitch (OVS) internal vport to a different net name space and subsequently deleting that name space led to a kernel panic. This bug has been fixed by removing the OVS internal vport at net name space deletion. (BZ#1202357) * Previously, the kernel audit subsystem was not correctly handling file and directory moves, leading to audit records that did not match the audit file watches. This fix correctly handles moves such that the audit file watches work correctly. (BZ#1202358) * Due to a regression, the crypto adapter could not be set online. A patch has been provided that fixes the device registration process so that the device can be used also before the registration pro ...
