UPDATED: Maintenance Pack 4 is now prerequisite. Previous releases
required update pack 2.
UnixWare 7.1.3 is unaffected by this issue because the
version of bind included in UnixWare 7.1.3 is 9.2.1.
Open UNIX is also unaffected by this issue because the version
of bind in Open UNIX 8.0.0 is 9.1.0.
CERT/CC Incident Note VU#734644
BIND is an implementation of the Domain Name System (DNS)
protocols. Successful exploitation of this vulnerability
may result in a temporary denial of service.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2003-0914 to this issue.

Alternatively, this SLS package may be installed in quiet mode,
that is, without displaying the release notes and asking for
confirmation. To do this, use these commands:
$ su
Password: <type your root password>
# uncompress /tmp/erg712479b.Z
# pkgadd -qd /tmp/erg712479b all
# rm /tmp/erg712479b
3. There is no need to reboot the system after installing this package.
