>   *) SECURITY: CVE-2023-27522: Apache HTTP Server: mod_proxy_uwsgi
>      HTTP response splitting (cve.mitre.org)
>      HTTP Response Smuggling vulnerability in Apache HTTP Server via
>      mod_proxy_uwsgi. This issue affects Apache HTTP Server: from
>      2.4.30 through 2.4.55.
>      Special characters in the origin response header can
>      truncate/split the response forwarded to the client.

>   *) SECURITY: CVE-2023-25690: HTTP request splitting with
>      mod_rewrite and mod_proxy (cve.mitre.org)
>      Some mod_proxy configurations on Apache HTTP Server versions
>      2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack.
>      Configurations are affected when mod_proxy is enabled along with
>      some form of RewriteRule
>      or ProxyPassMatch in which a non-specific pattern matches
>      some portion of the user-supplied request-target (URL) data and
>      is then
>      re-inserted into the proxied request-target using variable
>      substitution. For example, something like:
>      RewriteEngine on
>      RewriteRule "^/here/(.*)" "
>      http://example.com:8080/elsewhere?$1"
>      http://example.com:8080/elsewhere ; [P]
>      ProxyPassReverse /here/  http://example.com:8080/
>      http://example.com:8080/
>      Request splitting/smuggling could result in bypass of access
>      controls in the proxy server, proxying unintended URLs to
>      existing origin servers, and cache poisoning.

>   *) rotatelogs: Add -T flag to allow subsequent rotated logfiles to be
>      truncated without the initial logfile being truncated.  [Eric Covener]
> 
>   *) mod_ldap: LDAPConnectionPoolTTL should accept negative values in order to
>      allow connections of any age to be reused. Up to now, a negative value
>      was handled as an error when parsing the configuration file.  PR 66421.
