Subject:		UnixWare 7.1.3 UnixWare 7.1.1 : OpenSSL Multiple Vulnerabilities
Advisory number: 	SCOSA-2005.7
Issue date: 		2005 January 20
Cross reference:	sr890283 fz529411 erg712602 CAN-2004-0079 CAN-2004-0081 CAN-2004-0112

1. Problem Description

	OpenSSL implements the Secure Sockets Layer (SSL) and
	Transport Layer Security (TLS) protocols and includes a
	general purpose cryptographic library. SSL and TLS are
	commonly used to provide authentication, encryption,
	integrity, and non-repudiation services to network 
	applications including HTTP, IMAP, POP3, SMTP, and LDAP. 

	The U.K. National Infrastructure Security Co-ordination 
	Centre (NISCC) and the OpenSSL Project have reported several
	vulnerabilities in the OpenSSL SSL/TLS library (libssl). 
	Any application or system that uses this library may be 
	affected. 

	CERT Vulnerability Note VU#288574 
	OpenSSL contains null-pointer assignment in do_change_cipher_spec()
	function 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2004-0079 to this issue. 

	CERT Vulnerability Note VU#465542 
	OpenSSL does not properly handle unknown message types 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2004-0081 to this issue.

	CERT Vulnerability Note VU#484726
	OpenSSL does not adequately validate length of Kerberos ticket 
	during SSL/TLS handshake.  

	The Common Vulnerabilities and Exposures project (cve.mitre.org)
        has assigned the name CAN-2004-0112 to this issue.

2. Vulnerable Supported Versions

	System				Binaries
	----------------------------------------------------------------------
	UnixWare 7.1.4 			Not vulnerable
	UnixWare 7.1.3 			Distribution
	UnixWare 7.1.1 			Distribution


3. Solution

	The proper solution is to install the latest packages.

4. UnixWare 7.1.3

	4.1 Location of Fixed Binaries

	ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.7

	4.2 Verification

	MD5 (openssl.pkg) = d2ba4c1dee05dad681b39bfea4d4d7f9
	MD5 (openssld.pkg) = 6a737b8d0265e8194f55f39518380bae

	md5 is available for download from
		ftp://ftp.sco.com/pub/security/tools


	4.3 Installing Fixed Binaries
