(formerly known as Sun Java System Web Server) running on the remote 
host is 7.0.x prior to 7.0.23. It is, therefore, affected by a heap
buffer overflow condition in the ASN.1 decoder in the Network Security
Services (NSS) library. A remote attacker can exploit this, via
crafted OCTET STRING data, to cause a denial of service or to execute
arbitrary code.");
