			SCO Security Advisory

Subject:		Linux: buffer overflow in nss_ldap DNS SRV
Advisory number: 	CSSA-2002-058.0
Issue date: 		2002 December 10
Cross reference:
______________________________________________________________________________


1. Problem Description

	A buffer overflow in the DNS SRV code for nss_ldap allows remote
	attackers to cause a denial of service and possibly execute
	arbitrary code.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------

	OpenLinux 3.1.1 Server		prior to nss_ldap-172-5.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to nss_ldap-172-5.i386.rpm

	OpenLinux 3.1 Server		prior to nss_ldap-172-5.i386.rpm

	OpenLinux 3.1 Workstation	prior to nss_ldap-172-5.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.
