Subject:		Linux: buffer overflow in multiple DNS resolver libraries
Advisory number: 	CSSA-2002-034.0
Issue date: 		2002 August 05
Cross reference:
______________________________________________________________________________


1. Problem Description

	From CERT CA-2002-19: A buffer overflow vulnerability exists in
	multiple implementations of DNS resolver libraries. Operating
	systems and applications that utilize vulnerable DNS resolver
	libraries may be affected. A remote attacker who is able to
	send malicious DNS responses could potentially exploit this
	vulnerability to execute arbitrary code or cause a denial of
	service on a vulnerable system.


2. Vulnerable Supported Versions

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.
