HTTP Server, as follows:

  - In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be
    self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within
    the request URL. (CVE-2020-1927)

  - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a
    malicious FTP server. (CVE-2020-1934)
