			SCO Security Advisory

Subject:		OpenLinux: Bind: cache poisoning BIND 8 prior to 8.3.7 and BIND 8.4.x prior 8.4.2
Advisory number: 	CSSA-2004-003.0
Issue date: 		2004 February 19
Cross reference:	sr886764 fz528462 erg712477 CAN-2003-0914
______________________________________________________________________________


1. Problem Description

	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.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to bind-8.3.7-1.i386.rpm
					prior to bind-doc-8.3.7-1.i386.rpm
					prior to bind-utils-8.3.7-1.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to bind-8.3.7-1.i386.rpm
					prior to bind-doc-8.3.7-1.i386.rpm
					prior to bind-utils-8.3.7-1.i386.rpm


3. Solution

	The proper solution is to install the latest packages. Many
	customers find it easier to use the Caldera System Updater, called
	cupdate (or kcupdate under the KDE environment), to update these
	packages rather than downloading and installing them by hand.
