The definite_length_decoder function in lib/util/quickder.c in Mozilla
Network Security Services (NSS) before 220.127.116.11 and 3.17.x before
3.17.3 does not ensure that the DER encoding of an ASN.1 length is
properly formed, which allows remote attackers to conduct
data-smuggling attacks by using a long byte sequence for an encoding,
as demonstrated by the SEC_QuickDERDecodeItem function's improper
handling of an arbitrary-length encoding of 0x00.
