		Caldera International, Inc.  Security Advisory

Subject:		Linux: multiple vulnerabilities in openssl
Advisory number: 	CSSA-2002-033.0
Issue date: 		2002 July 31
Cross reference:
______________________________________________________________________________


1. Problem Description

	There are four remotely exploitable buffer overflows that affect
	various OpenSSL client and server implementations. There are also
	encoding problems in the ASN.1 library used by OpenSSL. Several
	of these vulnerabilities could be used by a remote attacker to
	execute arbitrary code on the target system. All could be used
	to create denial of service.


2. Vulnerable Supported Versions

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

	OpenLinux 3.1.1 Server		prior to openssl-0.9.6-18.i386.rpm
					prior to openssl-devel-0.9.6-18.i386.rpm
					prior to openssl-devel-static-0.9.6-18.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to openssl-0.9.6-18.i386.rpm
					prior to openssl-devel-0.9.6-18.i386.rpm
					prior to openssl-devel-static-0.9.6-18.i386.rpm

	OpenLinux 3.1 Server		prior to openssl-0.9.6-18.i386.rpm
					prior to openssl-devel-0.9.6-18.i386.rpm
					prior to openssl-devel-static-0.9.6-18.i386.rpm

	OpenLinux 3.1 Workstation	prior to openssl-0.9.6-18.i386.rpm
					prior to openssl-devel-0.9.6-18.i386.rpm
					prior to openssl-devel-static-0.9.6-18.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.
