Hi, The following vulnerability was published for undertow. CVE-2023-5379[0]: | A flaw was found in Undertow. When an AJP request is sent that | exceeds the max-header-size attribute in ajp-listener, JBoss EAP is | marked in an error state by mod_cluster in httpd, causing JBoss EAP | to close the TCP connection without returning an AJP response. This | happens because mod_proxy_cluster marks the JBoss EAP instance as an | error worker when the TCP connection is closed from the backend | after sending the AJP request without receiving an AJP response, and | stops forwarding. This issue could allow a malicious user could to | repeatedly send requests that exceed the max-header-size, causing a | Denial of Service (DoS). Only reference is https://bugzilla.redhat.com/show_bug.cgi?id=2242099 so far. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
