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: 1. Certain ASN.1 encodings that are rejected as invalid
            by the parser can trigger a bug in the deallocation
            of the corresponding data structure, corrupting the
            stack.  This can be used as a denial of service
            attack.  It is currently unknown whether this can be
            exploited to run malicious code. This issue does not
            affect OpenSSL 0.9.6.

            More details are available at:
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0545

         2. Unusual ASN.1 tag values can cause an out of bounds
            read under certain circumstances, resulting in a
            denial of service vulnerability.
            More details are available at:
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0543
   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0544

         3. A malformed public key in a certificate will crash
            the verify code if it is set to ignore public key
            decoding errors.  Exploitation of an affected
            application would result in a denial of service
            vulnerability.

         4. Due to an error in the SSL/TLS protocol handling,
            a server will parse a client certificate when one is
            not specifically requested.

IMPACT:   Potential Denial of Service

PLATFORM: HP9000 Servers running HP-UX releases B.11.00, B.11.11,
          and B.11.22, only with the BINDv920 installed.

**REVISED 01**
SOLUTION: Until a product upgrade is available, download and
          install the appropriate depot from the ftp site
          (see below).

      Bind9.2 for B.11.00         BIND920.11.00.depot
 -->  Bind9.2 for B.11.11         BINDv920 version 005
      Bind9.2 patch for B.11.22   PHNE_29859.depot

**REVISED 01**
MANUAL ACTIONS: Yes - NonUpdate
                for B.11.00 use the temporary depot
                for B.11.11 download web upgrade
                for B.11.22 use the temporary depot
                Install the product containing the fix.

AVAILABILITY: The depots or patch are available now, via ftp
              (see below).
              This bulletin will be updated when a product
              upgrade is available.
 -----------------------------------------------------------------
 A. Background
    An SSL/TLS testing suite developed by the NISCC (National
    Infrastructure Security Co-Ordination Centre in the UK) has
    identified ASN.1 parsing vulnerabilities in OpenSSL.


     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.

     HP-UX B.11.00
     =============
     BINDv920.INETSVCS-BIND
     fix: install revision B.11.00.01.002 from BIND920.11.00.depot

     HP-UX B.11.11
     =============
     BINDv920.INETSVCS-BIND
 --> fix: install revision B.11.11.01.005 or subsequent from
          <software.hp.com>.

     HP-UX B.11.22
     =============
     InternetSrvcs.INETSVCS2-RUN
     fix: install PHNE_29859.depot

     END AFFECTED VERSIONS


 B. Recommended solution
    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, instead are simply newer versions.

    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.
    If the version is anything other than 9.2.0, this bulletin
    does not apply to the system being examined.

    Until a product upgrade is available, download and install
    install the appropriate depot from the ftp site.

 -->  1a). For B.11.00 and B.11.22, download the appropriate
           .depot.gz from the ftp site.
         (This file is temporary and will be deleted when a
         product upgrade is available from itrc.hp.com).

        System:    hprc.external.hp.com  (192.170.19.51)
        Login:     bind920
        Password:  bind920

        FTP Access: ftp://bind920:bind920@xxxxxxxxxxxxxxxxxxxx/
                or: ftp://bind920:bind920@xxxxxxxxxxxxx/
                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:
                  [ ] Enable folder view for FTP sites

 -->  1b). For B.11.11 download BINDv920 version 005 from web
 -->       upgrade at: <http://software.hp.com>

     ==================================================
      2. To fix the problem, copy the appropriate depot file to
         a protected directory and unpack it.

     cksum:
           1691634068  8498721  BIND920.11.00.depot.gz
 -->       3043026926  8714240  BINDv920 version 005
           1640049049 12927378  PHNE_29859.depot.gz

               8AEF8700958CDAE6D50D0FCFE6B30FB6
 -->     BINDv920 version 005 from <http://software.hp.com>

               0B306B5E4353D157F0120B719D8D38D3

      3. Install the appropriate depot using swinstall(1).

 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
