TIBCO Enterprise Message Service vulnerability
Original release date: April 9, 2008
Last revised: --
Source: TIBCO Software Inc.
Systems Affected
TIBCO Enterprise Message Service (EMS) versions below 4.4.3
TIBCO iProcess Engine versions 10.6.0 thru 10.6.1
The following components are affected:
* TIBCO EMS Server (tibemsd)
Overview
The TIBCO EMS server contains buffer overflow vulnerabilities in the
processing of inbound data. The impact of these vulnerabilities may
include remote execution of arbitrary code, information disclosure,
and denial of service.
I. Description
TIBCO has released an update that addresses critical vulnerabilities
in the server component of TIBCO EMS.
The EMS server contains vulnerabilities that may allow an attacker to
compromise the server by sending a specially crafted message to the
EMS server via an EMS client connection or via the TIBCO Rendezvous
Daemon.
TIBCO strongly recommends sites running the affected component to
install the update or take mitigating action as appropriate.
II. Impact
The impact of these vulnerabilities varies depending on the operating
system, configuration options of the server, and the privilege
levels of the user that invokes the server.
On Unix based systems, a successful exploit will allow arbitrary
code execution with the privileges of the user that invoked the
server.
On Windows based systems, a successful exploit will allow
arbitrary code execution with the privileges of the user that
invoked the server. If the server component is installed as a
system service, this will result in access to system privileges.
III. Solution
Upgrade TIBCO Enterprise Messaging Service to version 4.4.3 or
above. This is strongly recommended.
If an upgrade is not possible, the following actions can mitigate
the vulnerabilities:
* Ensure that authorization is enabled in the EMS server and
that all authorized users defined locally or in LDAP are fully
trusted.
* Utilize a firewall to restrict access to the EMS server
port to trusted sources.
* Disable Rendezvous support by setting "tibrv_transports"
to "disabled" in the configuration file for the EMS server
(tibemsd.conf).
