This Linux kernel update for openSUSE 11.1 fixes lots of bugs and some security issues.

The kernel was also updated to the 2.6.27.21 stable release.

CVE-2009-1072: nfsd in the Linux kernel does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request. The fix for this was incomplete.

CVE-2009-0835: The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod.
