-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0381 -- [Win][UNIX/Linux][OSX] TIBCO Enterprise Message Service vulnerability 11 April 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: TIBCO Enterprise Message Service (EMS) versions below 4.4.3 TIBCO iProcess Engine versions 10.6.0 thru 10.6.1 Publisher: TIBCO Operating System: Windows UNIX variants (UNIX, Linux, OSX) Impact: Execute Arbitrary Code/Commands Denial of Service Access Confidential Data Access: Remote/Unauthenticated CVE Names: CVE-2008-1703 CVE-2008-1704 Original Bulletin: http://www.tibco.com/resources/mk/ems_security_advisory_20080409.txt - --------------------------BEGIN INCLUDED TEXT-------------------- 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).
