IMPACT: Possible execution of arbitrary local commands.

PLATFORM: Any system running HP Secure OS Software for Linux
          Release 1.0.

SOLUTION: Apply the appropriate patch.

AVAILABILITY: The RPMs are available now.
 ------------------------------------------------------------------

 A. Background

    PHP is an HTML-embedded scripting language commonly used with
    the Apache HTTP server. A vulnerability exists in versions up
    to and including 4.2.2 where an unauthorized user could execute
    arbitrary local commands.

 B. Recommended solution

    Hewlett-Packard Company recommends that customers install the
    RPMs listed in the following Red Hat Security Advisory in the
    section labeled "Red Hat Linux 7.1".

                              in mail function

    http://rhn.redhat.com/errata/RHSA-2002-213.html

    To install the security bulletin RPMs, use the following sequence
    of commands:

    1. If you use the tripwire product, we recommend that you run a
       a consistency check and fix any violations before installing
       the security bulletin RPM.

           tripwire --check --interactive

    2. Install the bulletin RPM from the root account.

           rpm -F <bulletin RPM name>

    3. Update the tripwire database

           tripwire --check --interactive

    NOTE:
    The rpm -q <package name> command can be used to determine if
    the package is installed. Hewlett-Packard Company recommends
    applying the Security Bulletin fixes to installed packages only.
    The -F option to the RPM installer will only apply the fix if the
    package is currently installed on the system. Dependent RPMs can be
    found by using the "Find Latest RPMs" search facility at
