-----BEGIN PGP SIGNED MESSAGE-----

Liebe Kolleginnen und Kollegen,

soeben erreichte uns das nachfolgende Update zu einem Bulletin der HP
SupportLine.  Wir geben diese Informationen unveraendert an Sie
weiter.

HP fuegt HP-UX B.11.04 zur Liste der betroffenen Systeme hinzu und
stellt Patch PHCO_30191 zur Verfuegung.

Zur Erinnerung:

HPSBUX0311-294   SSRT3656 NLSPATH 

 Setuid Root Programme, die den Funktionsaufruf catopen(3c) verwenden,
 beruecksichtigen die Pfade in der Umbebungsvariable NLSPATH. Ein
 lokaler Angreifer kann diese Schwachstelle durch eine entsprechend
 konstruierte NLSPATH u.U. ausnuzten, um beliebige Befehle mit
 erweiterten Privilegien auszufuehren.

    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@xxxxxxxxxxx>
    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.

    END AFFECTED VERSIONS

    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.

    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.
