-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0055 -- [Win][UNIX] TIBCO SmartSockets RTServer Multiple Vulnerabilities 16 January 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: TIBCO SmartSockets Publisher: iDEFENSE Operating System: Windows UNIX specific Impact: Execute Arbitrary Code/Commands Denial of Service Access: Remote/Unauthenticated CVE Names: CVE-2007-5655 CVE-2007-5656 CVE-2007-5657 CVE-2007-5658 Original Bulletin: http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=638 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=639 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=640 http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=641 Comment: This bulletin contains four (4) iDefense Security Advisories - --------------------------BEGIN INCLUDED TEXT-------------------- iDefense Security Advisory 01.15.08 http://labs.idefense.com/intelligence/vulnerabilities/ Jan 15, 2008 I. BACKGROUND TIBCO SmartSockets is a message passing framework used to transport messages over disparate channels. The RTserver is the server component of the framework. More information can be found on the vendor's web site at the following URL. http://www.tibco.com/software/messaging/smartsockets/ II. DESCRIPTION Remote exploitation of multiple untrusted loop bounds vulnerabilities in TIBCO Software Inc.'s SmartSockets RTserver may allow an attacker to crash the service or execute arbitrary code with SYSTEM privileges. When processing requests, SmartSockets uses values from the requests to control the number of iterations of several loops. Inside these loops, various memory operations are performed. Since attackers can control these values, potentially exploitable conditions arise. III. ANALYSIS Exploitation allows an attacker to execute arbitrary code with SYSTEM privileges. Unsuccessful attempts will likely crash the RTserver. The service does not restart, which makes repeated exploitation attempts more difficult. The RTserver is the core component of the SmartSockets framework. Without it, applications will be unable to pass messages. The severity of these issues will likely vary depending on the the application using the SmartSockets framework. IV. DETECTION iDefense has confirmed the existence of these vulnerabilities in TIBCO SmartSockets version 6.8.0. Previous versions may also be affected. V. WORKAROUND iDefense is currently unaware of any workarounds for these issues. VI. VENDOR RESPONSE TIBCO has addressed these vulnerabilities by releasing new versions of their software. For more information, consult their advisory at the following URL. http://www.tibco.com/mk/advisory.jsp VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2007-5656 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII. DISCLOSURE TIMELINE 10/23/2007 Initial vendor notification 12/04/2007 Second vendor notification 12/05/2007 Initial vendor response 01/15/2008 Public disclosure IX.

More information can be found on the vendor's web site at the following URL. http://www.tibco.com/software/messaging/smartsockets/ II. DESCRIPTION Remote exploitation of multiple untrusted pointer offset vulnerabilities in TIBCO Software Inc.'s SmartSockets RTserver may allow an attacker to crash the service or execute arbitrary code with SYSTEM privileges. When processing requests, SmartSockets uses values from the requests as offsets added to valid pointers. The resulting pointer values are then used in various memory operations. Since attackers can control these offset values, potentially exploitable conditions arise. III. ANALYSIS Exploitation allows an attacker to execute arbitrary code with SYSTEM privileges. Unsuccessful attempts will likely crash the RTserver. The service does not restart, which makes repeated exploitation attempts more difficult.

BACKGROUND TIBCO SmartSockets is a message passing framework used to transport messages over disparate channels. The RTserver is the server component of the framework. More information can be found on the vendor's web site at the following URL. http://www.tibco.com/software/messaging/smartsockets/ II. DESCRIPTION Remote exploitation of a heap overflow vulnerability in TIBCO Software Inc.'s SmartSockets RTserver may allow an attacker to crash the service or execute arbitrary code with SYSTEM privileges. A heap overflow vulnerability exists within the code responsible for processing requests. Two distinct values from the request are used for the allocation size and the amount of data copied. Since both values are attacker controlled, this can lead to a heap overflow, potentially resulting in the execution of arbitrary code. III. ANALYSIS Exploitation allows an attacker to execute arbitrary code with SYSTEM privileges. Unsuccessful attempts will likely crash the RTserver. The service does not restart, which makes repeated exploitation attempts more difficult. The RTserver is the core component of the SmartSockets framework.
