If mod_proxy_ajp connects to a malicious AJP server this AJP server can send a malicious AJP message back to mod_proxy_ajp and cause it to write 4 attacker controlled bytes after the end of a heap based buffer.  This issue affects Apache HTTP Server: through 2.4.66.  Users are recommended to upgrade to version 2.4.67, which fixes the issue.",
