Description

The Linux kernel is the core component of the Linux system. This update fixes various security as well as non-security problems discovered since the last round of kernel updates. Not all kernels are affected by all the problems, each of the problems has an affected note attached to it. The CAN-YYYY-NNNN IDs are Mitre CVE Candidate IDs, please see http://www.mitre.org for more information. The following security problems have been fixed: - local users could crash the system by causing stack fault exceptions (CAN-2005-1767) SUSE Linux 9.0 and SLES8 are affected. - local users could use ptrace to crash the kernel (CAN-2005-1761). SLES8 on the ia64 architecture is affected. - by causing an overflow in the 32bit execve function users could crash the kernel or even execute code (CAN-2005-1768). SLES 9 on the x86-64 and ia64 architectures and SUSE Linux 9.1 on the x86-64 architecture are affected. - an overflow when validating XDR data for the nfsacl protocol could crash the kernel. SUSE Linux 9.2 and 9.3 are affected. - local users could crash the kernel by reading from large offsets in sysfs files SUSE Linux 9.2 is affected. On SUSE Linux 9.1 this update contains the kernel used by the SUSE Linux Enterprise Server 9, Service Pack 2. This kernel adds among many bugfixes and driver updates support for non-executable pages (NX) on x86 CPUs and improves dual core CPU support.

Solution

There is no known workaround, please install the update packages.
