	* If the compiled file contents are the same as in already existing

	* [NEW PLATFORM] Compiled and tested on Linux @ alpha64 (LP64).
	  Some code needed to be fixed regarding int-long conversions
	  (mostly inside the test suite), and floating point handling
	  code needed to be restructured to handle signalling NAN and
	  other floating point exceptions quietly. Smooth transition!

106
	  (Severity: medium; Security impact: low).

	  When encoding data for certain ASN.1 specifications containing
	  explicit tags, the tag is always written incorrectly due to
	  incorrect memory reference. The encoding will almost always produce
	  unparseable data and might well reference unmapped region so program
	  would produce segmentation violation. Fortunately, memory is
	  read, not written, so remote exploits cannot execute arbitrary
	  code and triggering unmapped memory reference is highly unlikely
	  even it attacker knows the code (basically, the compiler should place
	  asn1_DEF_... right before the end of the mapped memory region, which
	  is extremely rare).

0.8.2:	2004-Mar-01	T-version-0-8-2

	* Fixed SEQUENCE BER decoder: an OPTIONAL element was required, where
	  should not have been (Severity: major; Security impact: low).
	* Fixed print_struct pointer inheritance.
	* Added -fno-c99 and -funnamed-unions

0.8.1:	2004-Feb-22

	* -R switch to asn1c: Omit support code, compile only the tables.
	* Introduced NativeInteger pseudotype.
	* Corrected the informal print_struct()'s output format.

0.8.0:	2004-Feb-03	T-version-0-8-0

	* Some documentation is created (a .pdf and a short manual page).
	* Last touches to the code.

0.7.9:	2004-Feb-01	T-version-0-7-9

	* Human readable printing support.
	* Support for implicit (standard) constraints.

0.7.8:	2004-Jan-31

	* SET now rejects duplicate fields in the data stream.

0.7.7:	2004-Jan-25

	* Added types: GeneralizedTime and UTCTime.

0.7.6:	2004-Jan-24	T-version-0-7-6

	* DER encoding of a SET OF now involves dynamic sorting.

0.7.5:	2004-Jan-24	T-version-0-7-5

	* DER encoding of a SET with untagged CHOICE
	  now involves dynamic sorting.

0.7.0:	2004-Jan-19	T-version-0-7-0

	* A bunch of DER encoders is implemented.

0.6.6:	2004-Jan-11

	* Implemented CHOICE decoder.
	* Implemented destructors support.

0.6.5:	2004-Jan-03

	* Implemented SET decoder.
	* Implemented SET OF and SEQUENCE OF decoders.

0.6.4:	2003-Dec-31

	* Implemented BOOLEAN, NULL, ENUMERATED decoders.
	* Implemented OCTET STRING decoder.
	* Implemented BIT STRING decoder.

0.6:	2003-Dec-30

	* First decoding of a BER-encoded structure!

0.5:	2003-Dec-28

	* Framework and most of the compiler backbone coding done.

0.1:	2003-Nov-28

	* Programming started.

=== Bug importance disclosure terms ===

SEVERITY.
    This term applies to the frequence the particular construct is used
    in the real world. The higher the frequency, the more chances of triggering
    this bug.
	low:	The ASN.1 specifications which could trigger
		this kind of bug are not widespread.
	medium:	The particular ASN.1 construct is used quite often,
		so the chance of triggering an error is considerable.
	high:	This fix is considered urgent, or the particular ASN.1
		construct triggering this bug is in wide use.

SECURITY IMPACT.
    This term applies to the amount of potential damage a bug exploitation
    could cause.
	low:	The local exploitation is unlikely; the remote exploitation
		is impossible.
	medium:	The remote exploitation is possible when a particular ASN.1
		construct is being used. If possible, only hard failure, spin
		or memory leak are the possible outcome: no shellcode
		injection could possibly be carried by the attack.
	high:	The remote shellcode injection is possible, or the bug is
		otherwise remotely exploitable for most specifications.
