  * SECURITY UPDATE: DoS or SSRF via forward proxy
    - debian/patches/CVE-2021-44224-1.patch: enforce that fully qualified

      the ones to be forward proxied have a hostname in
      include/http_protocol.h, modules/http/http_request.c,
      modules/http2/h2_request.c, modules/proxy/mod_proxy.c,
      modules/proxy/proxy_util.c, server/protocol.c.
    - debian/patches/CVE-2021-44224-2.patch: don't prevent forwarding URIs
      w/ no hostname in modules/proxy/mod_proxy.c,
      modules/proxy/proxy_util.c.
    - CVE-2021-44224
  * SECURITY UPDATE: overflow in mod_lua multipart parser

    - This extends an earlier fix for the start command to behave
      similarly for restart / graceful.  Fixes service failures on
      unattended upgrade.
