Important Security Notice for Customers Using
Products that Embed Ingres on Microsoft Windows ONLY

Issued: December 19, 2007

CA Technical Support is alerting customers to a potential vulnerability in the Ingres software that is embedded in various CA products. This vulnerability exists only on Ingres 2.5 and Ingres 2.6 on Windows, and does not manifest itself on any Unix platform. Ingres r3 and Ingres 2006 are not affected.

The vulnerability, CVE-2007-6334, is associated with users who connect after the first user being assigned the privileges and identity of the first user. In all reported instances, the application (typically an ASP.NET application using the Ingres ODBC driver) was running on Microsoft IIS Web server, and with the Integrated Windows Authentication (IWA) option enabled. While IWA is not enabled by default, it is a commonly used option. It should be noted that the Ingres .NET data provider is not affected.

Risk Rating

High

Affected Platforms

Windows

Affected Products

All CA products that embed Ingres 2.5 and Ingres 2.6

How to determine if you are affected

Check the %II_SYSTEM%\ingres\version.rel file to identify the Ingres version. If the installed version of Ingres 2.6 is a Double-Byte version (should have DBL referenced), please download the 2.6 Double-Byte patch. Otherwise, use the Single-Byte patch.

Remediation

The most prudent course of action for affected customers is to download and apply the corrective maintenance. Updates are required only for Ingres 2.6 and 2.5.

Potential problems installing the patches

While testing these patches, CA identified an install issue when the user is presented with the option to make a backup of the Ingres installation. In cases where a <space> is in the path, the path is not properly read. The backup does get taken and is by default stored in the %II_SYSTEM%\ingres\install\backup directory. Additionally, if the user happens to press the "Set Directory" button, the path will be displayed. Clicking "ok" will result in a message stating "... spaces are not supported in paths... ". This also is an error; pressing cancel will return the user to the first screen with the default path, and while the displayed path is terminated at a space, the actual path does work. To avoid this issue, use DOS 8.3 definitions (ex. C:\progra~1\CA\ingres).

Solution

Ingres has issued the following patches to address the vulnerabilities.

• Ingres 2.6 Single-Byte patch - Ingres 2.6 Single-Byte patch
• Ingres 2.6 Double-Byte patch- Ingres 2.6 Double-Byte patch
• Ingres 2.5 Single Byte Patch- Ingres 2.5 Single Byte patch
