     A. Background
        Superuser cannot restrict the paths set in the NLSPATH
        environment variable for setuid root programs which are
        using catopen(3C) and executed by others.

        The SSRT thanks NSFOCUS Security Team <security@nsfocus.com>
        for reporting this potential vulnerability to HP.

        NOTE: This problem does not impact HP NonStop Servers,
              HP OpenVMS nor HP Tru64 UNIX/Trucluster Server.

        AFFECTED VERSIONS

        The following is a list by HP-UX revision of
        affected filesets or patches and fix information.
        To determine if a system has an affected version,
        search the output of "swlist -a revision -l fileset"
        for an affected fileset or patch, then determine if
        a fixed revision or applicable patch is installed.

        NOTE: B.11.23 is not affected by this issue.

    **REVISED 01**
     B. Recommended solution
        Install the applicable patch and relink any suid root
        programs that are linked with archived libraries.

        Note: If libc patches are installed without rebooting,
              applications currently running which are linked
              shared against libc will still continue using the
              former version of libc. Rebooting will insure that
              all such applications will use the new libc.

        Download from <itrc.hp.com> the appropriate patch
        for the following HP-UX releases:

               B.11.22 PHCO_29329
               B.11.11 PHCO_29495
     --->> B.11.04 PHCO_30191
               B.11.00 PHCO_29284
               B.10.20 PHCO_26158

        Install using SD utilities.

        using your ID and password. Use your existing login or the

        "Register" button at the left to create a login, in order to
        gain access to many areas of the ITRC. Remember to save the
        User ID assigned to you, and your password.

        In the left most frame select "Maintenance and Support".

        Under the "Notifications" section (near the bottom of
        the page), select "Support Information Digests".

        To -subscribe- to future HP Security Bulletins or other
        Technical Digests, click the check box (in the left column)
        for the appropriate digest and then click the "Update
        Subscriptions" button at the bottom of the page.

        or

        To -review- bulletins already released, select the link
        (in the middle column) for the appropriate digest.

        To -gain access- to the Security Patch Matrix, select
        the link for "The Security Bulletins Archive". (near the
        bottom of the page) Once in the archive the third link is
        to the current Security Patch Matrix. Updated daily, this
        matrix categorizes security patches by platform/OS release,
        and by bulletin topic. Security Patch Check completely
        automates the process of reviewing the patch matrix for
        11.XX systems. Please note that installing the patches
        listed in the Security Patch Matrix will completely
        implement a security bulletin _only_ if the MANUAL ACTIONS
        field specifies "No."

        The Security Patch Check tool can verify that a security
        bulletin has been implemented on HP-UX 11.XX systems providing
        that the fix is completely implemented in a patch with no
        manual actions required. The Security Patch Check tool cannot
        verify fixes implemented via a product upgrade.

        For information on the Security Patch Check tool, see:
        http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/
        displayProductInfo.pl?productNumber=B6834AA

        The security patch matrix is also available via anonymous
        ftp:

        ftp://ftp.itrc.hp.com/export/patches/hp-ux_patch_matrix/
