"The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2009:1541 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.

    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)

    Users should upgrade to these updated packages, which contain a backported
    patch to correct these issues. The system must be rebooted for this update
    to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
