Overview

   TIBCO Rendezvous and EMS components listed above contain a SUID
   vulnerability which could potentially grant unauthorized root access
   to an attacker on Unix-based systems.


I. Description

   TIBCO has released updates that address a critical vulnerability
   in server components of TIBCO Rendezvous and EMS.  TIBCO strongly
   recommends sites running the affected components to install the
   update or take mitigating action as appropriate.


II. Impact

   On Unix-based systems a successful attack will result in a privilege
   escalation to root, granting the attacker full administrative control
   of the host.


III. Solution

   For each affected system, update to the corresponding software versions:

   TIBCO Rendezvous version 8.3.1 or higher
   TIBCO Enterprise Message Service 6.0.1 or higher
   TIBCO Runtime Agent (TRA) version 5.7.1 or higher
   TIBCO Silver BPM Service version 1.0.4 or higher
   TIBCO Silver CAP Service version 1.0.2 or higher
   TIBCO Silver BusinessWorks Service version 1.0.1 or higher

   This is strongly recommended.

   If an upgrade is not possible, the vulnerability can be completely
   mitigated by disabling SUID rights for all affected components.
