   Original release date: June 5, 2006
   Last revised: --
   Source: TIBCO Software Inc.


Systems Affected

   TIBCO Hawk versions below 4.6.1

   TIBCO Runtime Agent (TRA) versions below 5.4

   The following components are affected:

     * TIBCO Hawk HMA (tibhawkhma)


Overview

   The TIBCO Hawk Monitoring Agent contains a buffer overflow
   vulnerability in the configuration interface.  The impact of this
   vulnerability may allow a local attacker to execute arbitrary
   code with system privleges. 


I. Description

   TIBCO has released an update which address a critical vulnerability
   in the Hawk Monitoring Agent.  TIBCO strongly recommends sites
   running the Hawk Monitoring Agent to install the update or take
   mitigating action as appropriate.


II. Impact

   A local attacker who is able to modify the configuration of
   tibhawkhma may be able to execute arbitrary code with system
   privleges.

   If the tibhawkhma program is installed as suid root on a Unix
   system, the successful exploit will allow arbitrary code execution
   with root privileges.

   If the tibhawkhma program is installed as a system service on a
   Windows system, the successful exploit will allow arbitrary code
   execution with system service privileges.


III. Solution

   Upgrade TIBCO Hawk to version 4.6.1 or above.  This is strongly
   recommended.

   If an upgrade is not possible, taking all of the following steps
   will mitigate the vulnerability:

     * Set the permissions of the tibhawkhma configuration file
       such that only the system administrator may write to the
       configuration file.

     * Set the permissions of the tibhawkhma executable such that
       only the system administrator may launch the program.

     * On Unix systems, Set the permissions of the tibhawkhma
       executable such that it is not suid.
