+
+The function http_header_comp() should return the number of received
+headers, not only 0 on fail or 1 on success.
+
+Without this functionality, one could send more than the default
+of 16 headers and overflow the header array to craft a DoS as
+shown in nostromo CVE-2019-16279.
+
+This patch adds the missing header count functionality to the function
+http_header_comp().

+Mitigate nostromo CVE-2019-16278 (bypassing a check for /../ allowing
+execution of /bin/sh with arbitrary arguments).
+
+Nostromo as such handles encoded URI correctly but the strcutl()
+function in the string manipulation library removes 0x0d in the
+URI string resulting in a valid path. What should happen instead
+is that the decoded 0x0d character remains in the URI, resulting
+in an invalid path, giving rise to a 404.
