critical security updates :

CVE-2008-4307 Race condition in the do_setlk function in fs/nfs/file.c
in the Linux kernel before 2.6.26 allows local users to cause a denial
of service (crash) via vectors resulting in an interrupted RPC call
that leads to a stray FL_POSIX lock, related to improper handling of a
race between fcntl and close in the EINTR case.

CVE-2009-1337 The exit_notify function in kernel/exit.c in the Linux
kernel before 2.6.30-rc1 does not restrict exit signals when the
CAP_KILL capability is held, which allows local users to send an
arbitrary signal to a process by running a program that modifies the
exit_signal field and then uses an exec system call to launch a setuid
application.

CVE-2009-0834 The audit_syscall_entry function in the Linux kernel
2.6.28.7 and earlier on the x86_64 platform 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 certain
syscall audit configurations via crafted syscalls, a related issue to
CVE-2009-0342 and CVE-2009-0343.

CVE-2009-1336 fs/nfs/client.c in the Linux kernel before 2.6.23 does
not properly initialize a certain structure member that stores the
maximum NFS filename length, which allows local users to cause a
denial of service (OOPS) via a long filename, related to the
encode_lookup function.
