I.
A. Background
The CERT advisory (CA-99-14) 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:
ftp://info.cert.org/pub/cert_advisories/CA-99-14-bind.txt
B. Recommended solution
Apply the appropriate patches for BIND components noted below.
s700_800 HP-UX release 10.01, 10.10 & 10.20 BIND 4.9.7 PHNE_20618
s700_800 HP-UX release 10.24 (VVOS) BIND 4.9.7 PHNE_21288
s700_800 HP-UX release 11.00 BIND 4.9.7 PHNE_20619
s700_800 HP-UX release 11.04 (VVOS) BIND 4.9.7 PHNE_21090
The bind revision 8.1.2 upgrade is available for HP-UX 11.00 via
a web page:
http://www.software.hp.com/products/DNS_BIND/index.html
Registration for the download is necessary, once done, there is
a link for installation instructions underneath the download
button.
You have the an option of staying with bind 4.X or moving to
bind 8.X. The security holes mentioned in CERT advisory CA-99-14
have been fixed in both versions. Bind 8.X provides many
additional features. This is the latest version featuring full
support for negative caching (RFC2308) the clarifications in
RFC 2181, DNS security extensions in RFC 2065, multiple virtual
name servers, split DNS via "forward" zones, and general
enhancements. Please reference the web page above for full
details.
NOTE: There are some migration issues that need to be addressed,
but scripts are available which can ease the transition.
