The HTTPSTK service listening on port 8009 does not properly close connections after a simple TCP handshake.  This can lead to a buildup of CLOSE_WAIT connections and prevent legitimate access;  Eventually causing  the service to crash.

The exploit does not require authentication and takes down a key service of the Novell server..


Tentatively fixed in rpm novell-nrm-2.0.2-297.305.302.3 included in the OES-May-13 channel updates,  but still under testing/investigation.


Problem was that SSL_free and SSL_shutdown were not being called on erros. SSLsocket was being treated like a socket when it actually is a SSL connection.
