"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."
