"According to its self-reported version, the Oracle iPlanet Web Server
(formerly known as Sun Java System Web Server) running on the remote 
host is 6.1.x prior to 6.1.21 or 7.0.x prior to 7.0.22. It is,
therefore, affected by a flaw in the definite_length_decoder()
function in the Network Security Services (NSS) library due to a
failure to ensure that the DER encoding of an ASN.1 length is properly 
formed when handling PKCS#1 signatures. A remote attacker, by using a
long byte sequence for an encoding, can exploit this to conduct a
data-smuggling attack or inject arbitrary code.");
