This update fixes the following security issues :

- a NULL pointer dereference flaw was found in each of the
following functions in the Linux kernel:
pipe_read_open(), pipe_write_open(), and
pipe_rdwr_open(). When the mutex lock is not held, the
i_pipe pointer could be released by other processes
before it is used to update the pipe's reader and writer
counters. This could lead to a local denial of service
or privilege escalation. (CVE-2009-3547, Important)

The system must be rebooted for this update to take effect.
