**Name of the Vulnerable Software and Affected Versions** Oracle 9i Application Server Web Cache versions 9.0.0.4.0 through 9.0.4.0.0 **Description** A heap-based buffer overflow issue allows remote attackers to execute arbitrary code via a long HTTP request method header to the Web Cache listener. The issue arises from a long HTTP request method header sent to the Web Cache listener, which can lead to arbitrary code execution. **Recommendations** For Oracle 9i Application Server Web Cache versions 9.0.0.4.0 through 9.0.4.0.0, consider restricting access to the Web Cache listener to minimize the risk of exploitation until a patch is available. As a temporary workaround, avoid using long HTTP request method headers in the Web Cache listener. At the moment, there is no information about a newer version that contains a fix for this issue.
