This can be done by commenting out the `LoadModule xml2enc_module modules/mod_xml2enc.so` directive in the Apache HTTP Server configuration. A service restart is required for the change to take effect.\n\n```bash\n# Edit the Apache configuration file, e.g., /etc/httpd/conf.modules.d/00-base.conf\n# Comment out the line:\n# LoadModule xml2enc_module modules/mod_xml2enc.so\n\n# Reload the httpd service\nsudo systemctl reload httpd\n```\n\n*Note: Disabling `mod_xml2enc` will cause any configurations relying heavily on `mod_proxy_html` or raw HTML/XML encoding conversions to function incorrectly or fail. Red Hat strongly recommends upgrading to a patched version of `httpd` as soon as it becomes available for your specific RHEL channel.*"

Title
Apache HTTP Server: buffer overflow in mod_proxy_ajp via ajp_msg_check_header()
Summary
Heap-based Buffer Overflow vulnerability in mod_proxy_ajp of Apache HTTP Server.
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.

Title
Apache HTTP Server: mod_dav_lock indirect lock crash
Summary
A NULL pointer dereference in mod_dav_lock in Apache HTTP Server 2.4.66 and earlier may allow an attacker to crash the server with a malicious request.mod_dav_lock is not used internally by mod_dav or mod_dav_fs.
The only known use-case for mod_dav_lock was mod_dav_svn from Apache Subversion earlier than version 1.2.0.
Users are recommended to upgrade to version 2.4.66, which fixes this issue, or remove mod_dav_lock.

Title
Apache HTTP Server: mod_md (ACME), unintended retry intervals
Summary
An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30 days in default configurations), to the backoff timer becoming 0. Attempts to renew the certificate then are repeated without delays until it succeeds.
This issue affects Apache HTTP Server: from 2.4.30 before 2.4.66.
Users are recommended to upgrade to version 2.4.66, which fixes the issue.
