 -----------------------------------------------------------------
 A. Background

     CERT advisory CA-2002-19, CERT VU#738331, CERT VU#852283, and
     CERT VU#229595 report vulnerabilities which may affect
     products on HP-UX and VVOS.

    Note: These fixes should be applied to all systems using
          DNS, including those systems with client programs only.

     Notes on Bind Versions (B.11.00 and B.11.11)
     =============================================

     Bind is available on B.11.00 and B.11.11 as part of
     the base operating system and as a web upgrade.
     Both versions (base os and web upgrade) may be
     installed on a system simultaneously.  Only one
     version can be active.  The active version can
     be changed via a script.

     The base os versions are updated via patches.  The
     web upgrade versions are updated by installing a
     later web upgrade.  The web upgrade versions are
     not patched.

     If a web upgrade version is active it is not possible
     to patch the base os version.  It is necessary to
     switch to the base os version with the following
     command before applying the patch:

       /usr/bin/enable_inet -r bind

     If you are running a web upgrade version and do not
     intend to re-enable the base os version, it is not
     necessary to patch the base os version.  However,
     since the base os version can be re-enabled with
     the script, you may want to patch the base os version
     even though it is not active.  Similarly, if you have
     installed a web upgrade version and have switched
     back to the base os version, you may want to update
     to the latest web upgrade version or use swremove(1)
     to remove the web upgrade version entirely.

     Identifying the Active Version (B.11.00/B.11.11)
     ================================================

     Execute the following command:

        what /usr/sbin/named | grep named

     The bind version will be on the named line.
     For example:

         named 9.2.0 Thu Jul 18 11:58:39 GMT 2002


     Identifying the Web Upgrade Version (B.11.00/B.11.11)
     =====================================================

     If the file /usr/contrib/bind/usr/sbin/named exists,
     execute the following:

        what /usr/contrib/bind/usr/sbin/named | grep named

     The bind version will be on the named line.

     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.

     fix: libc.1.1010, libc.a.1010

     Note:  The Security Patch Check tool examines patches to
            determine whether a system is vulnerable.  Therefore,
            if the base o/s version of bind is not patched
            as described in this bulletin, the Security Patch
            Check tool will report that fact even if the
            web upgrade version is active.  The Security
            Patch Check tool will not examine the web upgrade
            versions of bind.

 B. Recommended solution

     CAUTION: If you have installed a web upgrade, the Base OS
              version remains on the system.  This command:
                 "/usr/bin/enable_inet -r bind"
              restores the Base OS version.  The Base OS version
              cannot be patched while the web upgrade version is
              enabled.  After reverting to the Base OS version
              you should verify that it is properly patched as
              described below.

     The following preliminary fixes are available:

     Note: On 10.10 and 10.20 the DNS API is contained in libc.
           Programs which make DNS calls and are linked with
           libc.a must be relinked.
           Programs which are linked with ".a" libraries
            are statically linked.
           Statically linked programs may be tested as follows:

      strings -a suspect_program | grep "Too many addresses (%d)"

           If the program contains the string it may make
           DNS API calls and should be relinked with the
           fixed version of libc.a.

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: Potental buffer overflow in xdrmem_getbytes() and
         related functions.

IMPACT: Potential unauthorized access, denial of service.

PLATFORM: HP-UX B.10.20, B.11.00, B.11.04, B.11.11, and B.11.22

SOLUTION: Until patches are available manually install the
          appropriate fixed libraries.  Preliminary patches
          are now available for B.11.00 and B.11.11 which
          eliminate the manual installation of all but libc.1.
          PHNE_28567(B.11.00) and PHNE_28568(B.11.11) provide a
          partial solution.  Please refer to the note below.

 -->      B.10.20 - PHCO_26158

MANUAL ACTIONS: Yes - NonUpdate
                Download and install the appropriate files.

AVAILABILITY:  The files are available now.  This bulletin will
               be revised when patches are available.

CHANGE SUMMARY: Rev.01 - Corrected instructions for replacing
                         libc.1 on 11.00 and 11.11.
                         Added CERT CA-2003-10 reference.
                Rev.02 - Corrected instructions 10.20
                Rev.03 - Patches are available for 11.00 and 11.11
                         libc.1 must still be manually installed
                         for 11.00 and 11.11
                Rev.04 - Corrected 11.00 and 11.11 patch
                         information.
                Rev.05 - Added note about general release patches
                Rev.06 - Added PHCO_26158.
                         Added AFFECTED VERSIONS section.

 -----------------------------------------------------------------
 A. Background

    There are potential buffer overflows in
    xdrmem_getbytes() and related functions.

    This issue has been reported by CERT/CC in
    advisory CA-2003-10.


    NOTE:
    The files listed below also have the fix for
    HPSBUX0209-215
    SSRT2336 Security Vulnerability in XDR library
    This bulletin should be implemented instead of
    HPSBUX0209-215.

    NOTE:

    The general release patches PHNE_28567 (B.11.00) and
    PHNE_28568 (B.11.11) contain the fix for some of the
    functions which are vulnerable.  The preliminary patches
    PHNE_28929(B.11.00) and PHNE_28930 (B.11.11) contain the fix
    for all the affected routines.  The routines fixed in
    PHNE_28567 and PHNE_28568 are thought to be more commonly
    used than the additional routines fixed in PHNE_28929 and
    PHNE_28930.  PHNE_28567 and PHNE_28567 are available now from
    <http://itrc.hp.com>.  If it is not possible to install
    preliminary patches there is some benefit to installing
    PHNE_28567 and PHNE_28568.

      Install libc.1 as follows:

      #DIR=[path to new files]
      #cd /usr/lib
      #cp $DIR/libc.1 libc.1.new
      #chmod 555 libc.1.new
      #chown bin:bin libc.1.new
      #mv libc.1 libc.1.orig
      #mv libc.1.new libc.1

      After this, any applications that use libnsl.1 must be
      restarted.  Any applications that use libnsl.a must
      be relinked and restarted.

      Rebooting is the recommended way to restart the applications
      using libnsl.1 or libc.1.


      For B.11.22 IA
      ====================================
      #DIR=[path to new files]
      #cd /usr/lib/hpux32
      #cp $DIR/libnsl.so.1.32_11.22.IA libnsl.so.1.new
