-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2007.0450 -- [Win] Ingres Database Multiple Heap Corruption Vulnerabilities 22 June 2007 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Ingres 2006 (version 9.0.4) CA Secure Content Manager Publisher: iDEFENSE Operating System: Windows Impact: Execute Arbitrary Code/Commands Overwrite Arbitrary Files Access: Remote/Unauthenticated CVE Names: CVE-2007-3334 Original Bulletin: http://supportconnectw.ca.com/public/ca_common_docs/ingresvuln_letter.asp Comment: Other products which use the Ingres 2006 database may also be vulnerable to this issue. - --------------------------BEGIN INCLUDED TEXT-------------------- Ingres Database Multiple Heap Corruption Vulnerabilities iDefense Security Advisory 06.21.07 http://labs.idefense.com/intelligence/vulnerabilities/ Jun 21, 2007 I. BACKGROUND Ingres is the database backend used by default in several CA products. The SCM (Secure Content Manager) is one of the products that uses Ingres. The SCM use Ingres to store quarantined virii and blocked HTTP requests/replies. For more information visit the following URLs. http://www3.ca.com/solutions/Product.aspx?ID=1013 http://www.ingres.com/ II. DESCRIPTION Remote exploitation of multiple heap overflow vulnerabilities in Ingres Database Server as distributed with Computer Associates International Inc.'s (CA) products may allow attackers to execute arbitrary code with SYSTEM privileges. The vulnerabilities exist in the Communications Server (iigcc.exe) and Data Access Server (iigcd.exe) components of Ingres. The Communications Server is the main component responsible for receiving and handling requests from the network. The Data Access Server is responsible for handling requests from the Ingres JDBC Driver and .NET data providers. These requests are decoded into Ingres internal formats and passed on to other components of the database server. The application does not properly validate the length of attacker supplied data before copying it into a fixed size heap buffer. This leads to an exploitable condition. III. ANALYSIS Exploitation allows an unauthenticated attacker to execute arbitrary code with SYSTEM privileges. In order to exploit this vulnerability an attacker would have to send a malformed request to the database server. This requires the ability to establish a TCP session on port 10916 (iigcc) or 10923 (iigcd). Exploitation has been demonstrated to be trivial. IV. DETECTION iDefense has confirmed the existence of this vulnerability in Ingres Database 3.0.3 as included with CA eTrust Secure Content Manager r8 on Windows. Previous versions may also be affected. In addition, any application that uses the Ingres Database may be vulnerable. V. WORKAROUND Employing firewalls or other access control methods can effectively reduce exposure to this vulnerability. VI. VENDOR RESPONSE CA has made fixes available for all supported CA products that embed Ingres. For more information consult CA's Security Alert at the following URL. http://supportconnectw.ca.com/public/ca_common_docs/ingresvuln_letter.asp VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2007-3334 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
