"According to its banner, the version of Apple Darwin Streaming Server
running on the remote host is prior to version 5.5.5. It is,
therefore, affected by multiple vulnerabilities :

  - A heap buffer overflow condition exists in the Apple
    Darwin Streaming Proxy that allows an unauthenticated,
    remote attacker, via multiple trackID values in a
    SETUP RTSP request, to cause application termination
    or the execution arbitrary code.
    (CVE-2007-0748)

  - Multiple stack-based buffer overflow conditions exist
    in the is_command() function within file proxy.c due
    to improper bounds checking. An unauthenticated, remote
    attacker can exploit these, via a long command or server
    value in an RTSP request, to cause application
    termination or the execution arbitrary code.
    (CVE-2007-0749)");
