Oracle Critical Patch Update - April 2007

Description

A Critical Patch Update is a collection of patches for multiple security vulnerabilities. It also includes non-security fixes that are required (because of interdependencies) by those security patches. Due to the threat posed by a successful attack, Oracle strongly recommends that fixes are applied as soon as possible. This Critical Patch Update contains 36 new security fixes across all products.

Patch Availability Table and Risk Matrices

The Oracle Database, Oracle Application Server, Oracle Enterprise Manager Grid Control, Oracle Collaboration Suite, Oracle E-Business Suite Applications (Release 12 only), JD Edwards EnterpriseOne, JD Edwards OneWorld Tools, PeopleSoft Enterprise Portal Applications and PeopleSoft Enterprise PeopleTools patches in the Updates are cumulative; each Critical Patch Update contains the fixes from the previous Critical Patch Updates.

Oracle E-Business Suite Applications Release 11i patches are not cumulative, so Oracle E-Business Suite Applications customers should refer to previous Critical Patch Updates to identify previous fixes they want to apply.

For each Oracle product being administered, please consult the documentation for patch availability information and installation instructions referenced from the following table. For an overview of the Oracle product documentation related to this Critical Patch Update, please refer to the Oracle Critical Patch Update April 2007 Documentation Map, MetaLink Note 420060.1.

Risk Matrix Content

Risk matrices list only security vulnerabilities that are newly fixed by the patches associated with this advisory. Risk matrices for previous fixes can be found in previous Critical Patch Update advisories.

Several vulnerabilities addressed in this Critical Patch Update affect multiple products. The same vulnerability appears with the same Vuln # in all risk matrices. Italics indicate vulnerabilities in code included from other product areas.

Oracle conducts an analysis of each security vulnerability addressed by a Critical Patch Update (CPU) or a Security Alert. Results of the security analysis are reflected in the associated documentation describing, for example, the type of vulnerability, the conditions required to exploit it and the result of a successful exploit. Oracle provides this information, in part, so that customers may conduct their own risk analysis based on the particulars of their product usage. As a matter of policy, Oracle does not disclose detailed information about an exploit condition or results that can be used to conduct a successful exploit. Oracle will not provide additional information about the specifics of vulnerabilities beyond what is provided in the CPU or Security Alert notification, the Patch Availability Matrix, the readme files, and FAQs. Oracle does not provide advance notification on CPU or Security Alerts to individual customers. Finally, Oracle distributes neither exploit code nor “proof-of-concept” code for product vulnerabilities.

Workarounds

Due to the threat posed by a successful attack, Oracle strongly recommends that fixes are applied as soon as possible. Depending on your environment, it may be possible to reduce the risk of successful attack by restricting network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from unprivileged users may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends changes are tested on non-production systems. Neither approach should be considered a long term solution as neither corrects the underlying problem.

Unsupported Products and De-Supported Versions

Unsupported products, releases and versions are not tested for the presence of vulnerabilities addressed by this Critical Patch Update. However, it is likely that earlier patch sets of affected releases are also affected by these vulnerabilities.

Supported products are patched in accordance with the Critical Patch Update policy summarized in the CPU Frequently Asked Questions document linked from the References section.

Critical Patch Update patches are available for customers who have purchased Extended Maintenance Support (EMS) before the implementation of the Lifetime Support Policy. De-support Notices indicate whether EMS is available for a particular release and platform, as well as the specific period during which EMS will be available.

Customers with valid licenses for product versions covered by Extended Support (ES), before the implementation of the Lifetime Support Policy, are entitled to download existing fixes; but new issues that may arise from the application of patches are not covered under ES. Therefore, ES customers should have comprehensive plans to enable removal of any applied patch.

Critical Patch Update patches are not provided for product versions which are no longer covered under the Extended Maintenance Support plan or the Lifetime Support Policy. We recommend that customers upgrade to the latest supported version of Oracle products in order to obtain patches.

Please review the "Extended Support" section within the Technical Support Policies for further guidelines regarding ES and EMS.

Advance Notice of On Request Model for Oracle Database and Oracle Application Server

In order to provide enhanced support to our customers, Oracle will proactively create patches only for platform/version combinations that, based on historical data, customers will download for the next Critical Patch Update. Beginning with the July 2007 Critical Patch Update, we will create patches for historically inactive platform/version combinations of the Oracle Database and Oracle Application Server only if requested by customers. Fixes for the vulnerabilities will continue to be included in future releases and patch sets.

Additional details regarding the products, versions and platforms that will be supported for the next Critical Patch Update and the process for requesting On Request patches are available in Section 3.8 (Planned Patches for Next CPU release) of the Critical Patch Update Availability Information for Oracle Server and Middleware Products (MetaLink Note 420061.1).

Modification History

Oracle Database Executive Summary

This Critical Patch Update contains a total of 14 new fixes for Oracle Database products, divided as follows:

• 13 new security fixes for the Oracle Database. Additionally, 1 new security fix for Oracle Enterprise Manager, 1 new security fix for Oracle Workflow Cartridge, and 1 new security fix for the Ultra Search component (see Secure Enterprise Search, below) affect code bundled with the Oracle Database. 2 of these vulnerabilities may be remotely exploitable without authentication, i.e. they may be exploited over a network without the need for a username and password. Of the 2, DB01 only affects Microsoft Windows platforms, and EM01 only affects Oracle Enterprise Manager functionality that is included in the Oracle9i Database. 2 new fixes are applicable to Oracle Database client-only installations, i.e. installations that do not have the Oracle Database installed.
• 1 new security fix for Oracle Secure Enterprise Search, which is a separate product that is not installed with the Oracle Database. The Oracle Database Ultra Search component contains code also present in the Oracle Secure Enterprise Search product, and both are potentially vulnerable.
• No new security fixes for Oracle HTTP Server. Oracle recommends applying this Critical Patch Update to Oracle HTTP Server installations which are affected by vulnerabilities fixed in prior Critical Patch Updates if the prior patches have not been applied. Oracle HTTP Server is an optional product that is not installed by default with the Oracle Database. If it has not been installed, this software will not be present and the Oracle HTTP Server patches are not required. Oracle Database versions up to and including Oracle Database 9i Release 2 allowed Oracle HTTP Server to be installed as an optional component of the database. Oracle Database versions 10g Release 1 and higher include Oracle HTTP Server on the Companion CD.
• No new security fixes for Oracle Application Express (formerly called HTML DB), but versions up to and including version 2.0 should be upgraded to the latest version. Oracle Application Express is an optional product that is not installed with the Oracle Database. If it has not been installed (it is provided on the Companion CD in the Oracle Database CD set for some Oracle Database versions), this software will not be present and the patches are not required. Please refer to Appendix A in the October 2006 Critical Patch Update advisory for more information.

Notes:

• DB01 and DB03 are specific to Microsoft Windows platforms. Other platforms are not vulnerable.
• EM01 only affects Oracle Enterprise Manager functionality that is included in the Oracle9i Database.
• SES01 is a vulnerability in the web interface to the Ultra Search component. It is potentially exploitable only if a web server, e.g. Oracle HTTP Server, has been installed and configured to make the web pages accessible.
• Vulnerabilities with a CVSS base score of 0.0 represent problems that are not exploitable in a default database environment. DB10 is a vulnerability in a package that by default is only available to privileged users. DB11, DB12 and DB13 are vulnerabilities in command line utilities that do not run with privilege. If custom code runs affected programs as a privileged user, it may allow malicious code to be run as that user.
• 9.0.1.5+ refers to Oracle Database 9i, version 9.0.1.5 FIPS+ which is only used in conjunction with Oracle Application Server 10g (9.0.4), version 9.0.4.3.

Oracle Database Client-only Installations

2 new database vulnerabilities addressed by this Critical Patch Update, DB11 and DB13, affect Oracle Database client-only installations (installations that do not have the Oracle Database installed). They are potentially exploitable where a privileged operating system process is passing input from an unprivileged source to the affected program. Oracle recommends applying this Critical Patch Update to client-only installations which may be using the affected programs in this way, or which are affected by client-only issues fixed in prior Critical Patch Updates if the prior patches have not been applied.

Client-side software in the middle tier is patched as part of the general middle tier patch and customers do not need to apply additional patches. Exceptions will be documented in the Patch Availability Document for Oracle Server and Middleware Products, or the Pre-Installation Note, depending on the product.

Upgrading Oracle Secure Enterprise Search

Oracle Secure Enterprise Search 10g is a standalone product that enables searching across a corporation's enterprise information assets. Unless you installed the Oracle Secure Enterprise Search product, it will not be present on your system and no further action is required. The security vulnerability listed in the risk matrix above is fixed in Oracle Secure Enterprise Search 10g Release 1, version 10.1.8. Customers on previous versions of Secure Enterprise Search should upgrade to version 10.1.8. Instructions on upgrading can be found in the Online Documentation. This and the software to install is referenced from the Oracle Technology Network Secure Enterprise Search page, on:
http://www.oracle.com/technology/software/products/search/index.html.

Oracle Application Server Executive Summary

This Critical Patch Update contains 5 new security fixes for Oracle Application Server. 1 Oracle Workflow Cartridge fix and 1 Oracle Secure Enterprise Search fix also affect Oracle Application Server. 2 vulnerabilities may be remotely exploitable without authentication, i.e. they may be exploited over a network without the need for a username and password. No new fixes are applicable to client-only installations, i.e. installations that do not have Oracle Application Server installed.

Oracle Application Server products that are bundled with the Oracle Database are affected by the vulnerabilities listed in the Oracle Database section. They are not discussed further in this section and are not listed in the Oracle Application Server risk matrix. Oracle Application Server 10g Release 2 (10.1.3.0.0) is not affected by Application Server specific vulnerabilities, but includes Oracle Database code that needs to be patched by applying the Oracle Application Server patch.
