POTENTIAL SECURITY IMPACT:    local elevation of privilege by an
                              authorized user

HP Software Security Response Team


A potential vulnerability has been identified with HP-UX where
directory permissions may be locally exploited to allow an
authorized user to gain elevated privileges.

SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.
HP-UX B.11.00,  HP-UX B.11.04,  HP-UX B.11.11.

    World writable permissions on certain directories potentially
    allow a local user to gain root privileges.  The permissions
    of the following directories should be 775 instead of 777:


   Note: After the patches are applied only the root user will
         be able to run catman(1m) for /usr/share/man.

   Note:  If the B.11.00 patch is installed and the system is
           upgraded to B.11.11, swverify will report an error
           until the corresponding B.11.11 patch is installed.
           The permissions will remain safe, but until the B.11.11
           patch is installed they will not be the permissions
           that swverify expects.


     Note: To determine if a system has an affected version,
           search the output of "swlist -a revision -l fileset"
           for an affected fileset.  Then determine if the
           recommended patch or update is installed.

     HP-UX B.11.00
     action: install PHCO_29621 or subsequent

     HP-UX B.11.04
     action: install PHCO_30519 or subsequent

     HP-UX B.11.11
     action: install PHCO_29622 or subsequent


    Please install the appropriate patch:

         HP-UX B.11.00 - PHCO_29621 or subsequent
         HP-UX B.11.04 - PHCO_30519 or subsequent
         HP-UX B.11.11 - PHCO_29622 or subsequent

The HP-UX Security Patch Matrix, updated daily, categorizes
security patches by platform/OS release, and by Bulletin topic.
The Security Patch Check tool completely automates the process of
reviewing the Security Patch Matrix for HP-UX 11.XX Versions.
NOTE: Installing patches listed in the Security Patch Matrix will
completely implement the RESOLUTION in the Security Bulletin
_only_ if there are no MANUAL ACTIONS included.

The Security Patch Check tool can also verify that a Security
Bulletin RESOLUTION has been implemented on HP-UX 11.XX Versions
provided that no MANUAL ACTIONS were included. The Security Patch
Check tool cannot verify patches implemented via product upgrade.
