                        SCO Security Advisory

Subject:                OpenServer 5.0.6 OpenServer 5.0.7 : OpenSSL Multiple 
Vulnerabilities
Advisory number:        SCOSA-2004.10
Issue date:             2004 July 29
Cross reference:        sr890284 fz529412 erg712603 TA04-078A VU#288574 
VU#465542 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
        ----------------------------------------------------------------------
        OpenServer 5.0.6                OpenSSL distribution
        OpenServer 5.0.7                OpenSSL distribution

3. Solution

        The proper solution is to install the latest packages.

        SCOSA-2004.10 is an update of gwxlibs to version 1.3.3Db.
