             are using catopen(3C) and executed by others.

    IMPACT: Increase in privilege.

    **REVISED 01**
    PLATFORM: HP9000 servers running HP-UX releases B.10.20, B.11.00,
              B.11.04, B.11.11, and B.11.22 only.

    **REVISED 01**
    SOLUTION: Download and apply 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


    AVAILABILITY: All patches are available now on <>
    CHANGE SUMMARY: Rev. 1 Added B.11.04 patch
    **REVISED 01**
     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 <>
        for reporting this potential vulnerability to HP.

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


        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.

         HP-UX B.11.22
         fix: install PHCO_29329 or subsequent

         HP-UX B.11.11
         fix: install PHCO_29495 or subsequent

     --> HP-UX B.11.04
     --> =============
     --> OS-Core.C-MIN
     --> OS-Core.C-MIN-64ALIB
     --> OS-Core.CORE-64SLIB
     --> OS-Core.CORE-SHLIBS
     --> ProgSupport.PROG-AUX
     --> ProgSupport.PROG-AX-64ALIB
     --> ProgSupport.PROG-MIN
     --> fix: install PHCO_30191 or subsequent

         HP-UX B.11.00
         fix: install PHCO_29284 or subsequent

         HP-UX B.10.20
         fix: install PHCO_26158 or subsequent


        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 <> 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.

        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:

        The security patch matrix is also available via anonymous

        On the "Support Information Digest Main" page:
