Executive Summary

This vulnerability is a buffer over-read issue in the Apache HTTP Server. It occurs when the server makes outbound OCSP (Online Certificate Status Protocol) requests to an attacker-controlled OCSP server.

The affected versions are Apache HTTP Server from 2.4.0 through 2.4.67. The issue is fixed in version 2.4.68.

Impact Analysis

A buffer over-read vulnerability can allow an attacker to read memory beyond the intended buffer boundaries. In this case, by controlling the OCSP server that Apache HTTP Server queries, an attacker could potentially cause the server to read sensitive memory data.

This could lead to information disclosure or other unintended behavior depending on what data is exposed.

Mitigation Strategies

Users are recommended to upgrade Apache HTTP Server to version 2.4.68, which fixes the buffer over-read vulnerability related to outbound OCSP requests.
