   DOCUMENT ID: 57475
   SYNOPSIS: SunPlex (Sun Cluster) Multiple Security Vulnerabilities in
   OpenSSL Secure Sockets Layer (SSL) and Transport Layer Security (TLS)
   Protocols
   DETAIL DESCRIPTION:
   
Sun(sm) Alert Notification

     * Sun Alert ID: 57475
     * Synopsis: SunPlex (Sun Cluster) Multiple Security Vulnerabilities
       in OpenSSL Secure Sockets Layer (SSL) and Transport Layer Security
       (TLS) Protocols
     * Category: Security
     * Product: Sun Cluster
     * BugIDs: 4959521
     * Avoidance: Workaround, T-Patch
     * State: Engineering Complete
     * Date Released: 16-Jan-2004
     * Date Closed:
     * Date Modified: 09-Feb-2004
       
1. Impact

   On systems running Sun Cluster 3.x with SunPlex Manager configured, a
   remote unprivileged user (who has obtained "root" privileges) may
   cause a Denial of Service (DoS) and arbitrary code execution due to
   multiple vulnerabilities in OpenSSL Secure Sockets Layer (SSL) and
   Transport Layer Security (TLS) protocols.
   
   This issue is also described in CERT Vulnerability VU#104280 at
   [1]http://www.kb.cert.org/vuls/id/104280, which is referenced in CERT
   Advisory CA-2003-26 at
   [2]http://www.cert.org/advisories/CA-2003-26.html. Also see the NISCC
   Vulnerability Advisory 006489/TLS at
   [3]http://www.uniras.gov.uk/vuls/2003/006489/tls.htm.
   
2. Contributing Factors

   This issue can occur in the following releases:
   
   SPARC Platform
     * Sun Cluster 3.0 (for Solaris 8) with SunPlex Manager configured
     * Sun Cluster 3.0 (for Solaris 9) with SunPlex Manager configured
     * Sun Cluster 3.1 (for Solaris 8) with SunPlex Manager configured
     * Sun Cluster 3.1 (for Solaris 9) with SunPlex Manager configured
       
   Notes:
    1. Sun Cluster 3.x is not supported on Solaris 7 or Solaris x86
       platforms.
    2. Sun Cluster 2.x is not affected by this issue.
    3. Sun Cluster component SunPlex Manager uses OpenSSL.
       
   To determine if SunPlex Manager is configured and running on a cluster
   node, run the following command:
    $ /usr/bin/ps -fp `/usr/bin/cat /var/cluster/spm/httpd.pid`


   If the output is similar to the following:
    UID   PID   PPID   C   STIME TTY  TIME  CMD
    root  2907     1   0   Nov 19 ?   0:02  /usr/apache/bin/httpd -DSSL -f /opt
/SUNWscvw/conf/httpd.conf

   then SunPlex Manager is running on this cluster node. If the above
   command returns no process information or an error, SunPlex Manager is
   not running on this cluster node.
   
3. Symptoms

   There are no predictable symptoms that would indicate the above
   described issue has been exploited.
   SOLUTION SUMMARY:
   
4. Relief/Workaround

   To work around the described issue, systems can be protected by
   completely stopping the SunPlex Manager by running the following
   command:
    $ /etc/init.d/initspm stop

   The following T-patches are available through normal support channels
   for the following releases:
   
   SPARC Platform
     * Sun Cluster 3.0 (for Solaris 8) T-Patch T113505-02
     * Sun Cluster 3.0 (for Solaris 9) T-Patch T113508-02
     * Sun Cluster 3.1 (for Solaris 8) T-Patch T115054-01
     * Sun Cluster 3.1 (for Solaris 9) T-Patch T115055-01
       
5. Resolution

   A final resolution is pending completion.
