Subject [Bug 60448] New: mod_fcgid leaks out Variable- prefixed FcgidAuthenticator response headers

            Bug ID: 60448
           Summary: mod_fcgid leaks out Variable- prefixed
                    FcgidAuthenticator response headers
           Product: Apache httpd-2
           Version: 2.4.6
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_fcgid
          Assignee: bugs@httpd.apache.org
          Reporter: ujvari@microsec.hu
  Target Milestone: ---

mod_fcgid passes "Variable-" prefixed headers, which were received from a
FcgidAuthenticator process, to the responder subprocess as environment
variable. These headers should not be sent back to the user, since these are
just internal data, but mod_fcgid let them through.

mod_fcgid seems to collect response headers in a r->err_headers_out field,
including "Variable-" prefixed ones, then mod_fcgid_modify_auth_header function
(called by an apr_table_do iterator) stores them in the subprocess environment
array. When mod_fcgid_modify_auth_header finds a "Variable-" prefixed header it
should remove it from the r->err_headers_out field I presume.
