Multiple vulnerabilities exist in Oracle software that may lead to execution of arbitrary code; the ability to read, modify, or delete information stored in underlying Oracle databases; or denial of service. All of these vulnerabilites were discovered by Next Generation Security Software Ltd.

I. Description

Multiple vulnerabilities exist in Oracle software products. The majority of these vulnerabilities are buffer overflows.

Oracle has published Security Alerts describing these vulnerabilities. If you use Oracle products listed in the "Systems Affected" section of this document, we strongly encourage you to review the following Oracle Security Alerts and apply patches as appropriate: NGSSoftware Insight Security Research Advisories describing these issues are listed below:

The CERT/CC has published vulnerability notes for each of these issues as well. The vulnerability in Oracle's mod_dav module (VU#849993) has been as assigned CVE ID CAN-2002-0842.

II. Impact

Depending on the vulnerability being exploited, an attacker may be able to execute arbitrary code; read, modify, or delete information stored in underlying Oracle databases; or cause a denial of service. The vulnerabilities in "ORACLE.EXE" (VU#953746) and the WebDAV modules (VU#849993, VU#511194) may be exploited prior to authentication.

III. Solution

Apply a patch

Solutions for specific vulnerabilities can be found in the above referenced Oracle Security Alerts, NGSSoftware Insight Security Research Advisories, and individual CERT/CC Vulnerability Notes.

Mitigation Strategies

Until a patch can be applied, the CERT/CC recommends that vulnerable sites
  • disable unnecessary Oracle services
  • run Oracle services with the least privilege
  • restrict network access to Oracle services
