 -----------------------------------------------------------------

NOTICE: There are no restrictions for distribution of this
Bulletin provided that it remains complete and intact.

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.

 -----------------------------------------------------------------
PROBLEM: The error messages returned by rpc.mountd can be used to
         determine whether a file exists.

IMPACT: Potential unauthorized information disclosure.

PLATFORM: HP-UX releases B.11.00, B.11.11, and B.11.22.

SOLUTION: Install replacement nfs.mountd file.

MANUAL ACTIONS: Yes - NonUpdate
                Install replacement rpc.mountd file.

AVAILABILITY:  The files are available now via ftp.

CHANGE SUMMARY: Rev.01 -  Replaced rpc.mountd.11.22 with
                          rpc.mountd.11.22.r1.
 -----------------------------------------------------------------
 A. Background
    This potential vulnerability has been publicly reported:
    <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-1999-1225>

**REVISED 01**
 -->Note: The original file supplied for B.11.22 will abort.  It
 -->      has been replaced by rpc.mountd.11.22.r1.


     AFFECTED VERSIONS

     The following is a list by HP-UX revision of
     affected filesets and the fileset revision or
     patch containing the fix.  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
     a fixed revision or the applicable patch is
     installed.

     HP-UX B.11.22
     =============
     NFS.NFS2-SERVER
     fix: install rpc.mountd

     HP-UX B.11.11
     =============
     NFS.NFS-SERVER
     fix: install rpc.mountd

     HP-UX B.11.00
     =============
     NFS.NFS-SERVER
     fix: install rpc.mountd

     END AFFECTED VERSIONS


 B. Recommended solution

    It is recommended that B.11.00 and B.11.11 have the
    following patches installed before installing the
    new rpc.mountd.

      HP-UX B.11.00 - PHNE_28567
      HP-UX B.11.11 - PHNE_28568

    Note:  All the files mentioned for download below are
           available from the following ftp site:

        System:    hprc.external.hp.com  (192.170.19.51)
        Login:     rpcmd
        Password:  rpcmd

        FTP Access: ftp://rpcmd:rpcmd@hprc.external.hp.com/
                or: ftp://rpcmd:rpcmd@192.170.19.51/
                or: ftp hprc.external.hp.com

        Note: There is an ftp defect in IE5 that may result in
               a browser hang.  To work around this:
        - Select Tools -> Internet Options -> Advanced
        - Un-check the option:
        - Un-check the option:
                  [ ] Enable folder view for FTP sites

       a. Download the files into a protected directory
          such as /etc.

       b. Verify the cksum or the md5 sum.

          cksum:
    1918843242 49152 rpc.mountd.11.00
    1875800265 49152 rpc.mountd.11.11
**REVISED 01**
 -->1456914671 205848 rpc.mountd.11.22.r1

    MD5 (rpc.mountd.11.00) = 6269e2fe7f9f1af5c290ffa5350c9429
    MD5 (rpc.mountd.11.11) = 35b7ad91905614437c3f3b7711f64d4f
**REVISED 01**
 -->MD5 (rpc.mountd.11.22.r1) = 6949d6572347125317d78bffdb19ba00

     Note: If you wish to verify the md5 sum and you do not
           have a copy of md5, please refer to:
               HPSBUX9408-016
               Patch sums and the MD5 program
     Note: Using your itrc account security bulletins can be
          found here:
     http://itrc.hp.com/cki/bin/doc.pl/screen=ckiSecurityBulletin

     c. Install the appropriate file.

        These files can be installed on an active system.
        However, there will be a delay to clients attempting
        to mount NFS filesystems from this server.

        Stop the rpc.mountd process
        # ps -ef|grep rpc.mountd
        # kill <PID>
        -or-
        Stop the NFS server
        # /sbin/init.d/nfs.server stop

        cd to the directory containing the new rpc.mountd.

        HP-UX B.11.00
        =============
        chown bin:bin rpc.mountd.11.00
        chmod 544 rpc.mountd.11.00
        mv /usr/sbin/rpc.mountd /usr/sbin/rpc.mountd.orig
        mv rpc.mountd.11.00 /usr/sbin/rpc.mountd

        HP-UX B.11.11
        =============
        chown bin:bin rpc.mountd.11.11
        chmod 544 rpc.mountd.11.11
        mv /usr/sbin/rpc.mountd /usr/sbin/rpc.mountd.orig
        mv rpc.mountd.11.11 /usr/sbin/rpc.mountd

**REVISED 01**
        HP-UX B.11.22
        =============
 -->    chown bin:bin rpc.mountd.11.22.r1
 -->    chmod 544 rpc.mountd.11.22.r1
 -->    mv /usr/sbin/rpc.mountd /usr/sbin/rpc.mountd.orig
 -->    mv rpc.mountd.11.22.r1 /usr/sbin/rpc.mountd


        Re-start the rpc.mountd process.
        If rpc.mountd were manually killed:
          # /usr/sbin/rpc.mountd
        If the NFS server were stopped:
          # /sbin/init.d/nfs.server start

    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
