ISSUE:    The CERT advisories CA-2001-02 and CA-2000-20 detailed
          several BIND vulnerabilities including buffer overflows,
          input validation error, and disclosure environment
          variables and denial of service.
          See:
            http://www.cert.org/advisories/CA-2001-02.html
              and
            http://www.cert.org/advisories/CA-2000-20.html .

          The Internet Software Consortium has posted information
          about all vulnerabilities at the following URL:

            http://www.isc.org/products/BIND/bind-security.html

PLATFORM:  HP9000 servers and workstations running HP-UX releases
           11.11, 11.00, 11.04, 10.20, 10.24, 10.10, and 10.01.

POSSIBLE RESULT: May allow remote users to  disrupt normal operation
                 on the DNS servers, other services could be
                 impacted if these vulnerabilities are exploited.

SOLUTION: Apply patches for HP-UX releases as follows:
                 for 11.00:           PHNE_23274  (BIND 4.9.7)
                     11.00:            *          (BIND 8.1.2)
                     11.11:           PHNE_23275  (BIND 8.1.2)
                     11.04:           PHNE_22919  (BIND 4.9.7)
                     10.20:           PHNE_23277  (BIND 4.9.7)
                     10.24:           PHNE_23439  (BIND 4.9.7)
                     10.10:           PHNE_23277  (BIND 4.9.7)
                     10.01:           PHNE_23277  (BIND 4.9.7)

I.
    A. Background
       The CERT advisories (CA-2001-02, and CA-2000-20) detailed several
       BIND vulnerabilities.
       The Berkeley Internet Name Domain (BIND) is an implementation of
       the Domain Name System (DNS) protocols. Complete details can be
       found at:  http://www.cert.org/advisories/CA-2001-02.html and
                  http://www.cert.org/advisories/CA-2000-20.html .

    B. Recommended solution

       The problem can be fully resolved by applying the appropriate
       patches to the system from http://itrc.hp.com.
        For HP-UX releases
                     11.00:           PHNE_23274  (BIND 4.9.7)
                     11.00:            *          (BIND 8.1.2)
                     11.11:           PHNE_23275  (BIND 8.1.2)
                     11.04:           PHNE_22919  (BIND 4.9.7)
                     10.20:           PHNE_23277  (BIND 4.9.7)
                     10.24:           PHNE_23439  (BIND 4.9.7)
                     10.10:           PHNE_23277  (BIND 4.9.7)
                     10.01:           PHNE_23277  (BIND 4.9.7)
