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
