Subject: UnixWare 7.1.1 : Bind: cache poisoning BIND 8 prior to
8.3.7 and BIND 8.4.x prior 8.4.2
Advisory number: CSSA-2003-SCO.33.1
Issue date: 2003 December 01
Cross reference: sr886768 fz528464 erg712479 CAN-2003-0914

1. Problem Description
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.
