The memory pools maintained by the server make this vulnerabilty hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk. Mitigation: All httpd users should upgrade to 2.4.30 or later. Credit: The issue was discovered by Robert Swiecki, bug found by honggfuzz References: https://httpd.apache.org/security/vulnerabilities_24.html
