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.

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

        Upgrade the affected binaries with the following sequence:

        Download openssl.pkg to the /var/spool/pkg directory

        # pkgadd -d /var/spool/pkg/openssl.pkg


5. UnixWare 7.1.1

        5.1 Location of Fixed Binaries

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

        The fixes are also available in SCO UnixWare Release 7.1.1
        Maintenance Pack 5 or later.  See
        ftp://ftp.sco.com/pub/unixware7/uw711pk/uw711mp5.txt

        5.2 Verification

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

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


        5.3 Installing Fixed Binaries

        Upgrade the affected binaries with the following sequence:

        Download openssld.pkg to the /var/spool/pkg directory

        # pkgadd -d /var/spool/pkg/openssld.pkg
