vlm67d57fe2005-03-06 09:29:03 +00003
4 * Fixed a name clash in produced constraint checking code.
vlm24b7eb12005-03-06 09:31:59 +00005 * #includes are now in single quotes (to solve a name
6 clash with system's <time.h> on a Win32 system).
vlm4df9cc12005-03-09 22:19:25 +00007 * Small refinement of XML DTD generation (`asn1c -X`).
8 * Relaxed XER processing rules to skip extra whitespace
9 in some more places. It also skips XML comments (although
vlmbe7a5322005-03-10 11:50:12 +000010 XML comments in XER are prohibited by X.693, #8.2.1).
vlm4df9cc12005-03-09 22:19:25 +000011 (Test case 70) (Severity: medium, Security impact: none)
12 Reported by <Dominique.Nerriec@alcatel.fr>.
vlmb04419e2005-03-10 11:27:28 +000013 * Constraints on primitive types being defined are now supported.

vlmdca48302005-03-03 21:29:10 +000017
vlm4fff94d2005-03-04 09:01:15 +000018 * Released -fcompound-names to fix the name clashes in the code
19 produced by the asn1c.
vlm9f554a32005-03-05 00:33:27 +000020 * Released -fno-include-deps to avoid #including non-critical
21 external dependencies.
22 * Compiler is taught to produce compilable code for yet another class
23 of circular ASN.1 type references.
vlm9a89df62005-03-04 11:18:59 +000024 * X.693:8.3.4 prohibits anything but SignedNumber; fixed XER codec.
25 * Fixed ENUMERATED identifier to value conversion in XER.
vlm560eeb82005-03-04 11:20:17 +000026 Reported by <jacque.celaire@caramail.com>.
vlm4fff94d2005-03-04 09:01:15 +000027 * If the compiled file contents are the same as in already existing
28 file (left from previous compilation), the old file is retained.
29 This prevents thrashing `make` dependencies if amount of changes in
30 the original ASN.1 module(s) is small.

vlmd7f47c02005-02-22 08:14:24 +000046 * Compiler now checks for duplicate ASN.1 types across modules.
vlm54af01c2005-01-17 15:27:47 +000047
vlm34dcd572005-01-17 11:40:49 +0000480.9.8: 2005-Jan-17
vlm0aa86902004-10-12 23:26:53 +000049
vlm32d29a52004-10-26 10:44:18 +000050 * [NEW PLATFORM] Compiled and tested on Linux @ alpha64 (LP64).
51 Some code needed to be fixed regarding int-long conversions
52 (mostly inside the test suite), and floating point handling
53 code needed to be restructured to handle signalling NAN and
54 other floating point exceptions quietly. Smooth transition!
55 * [NEW PLATFORM] Compiled and tested on Sun Solaris 9 @ sparc.
56 Improved includes/defines of/for system headers.

vlm34dcd572005-01-17 11:40:49 +000063 * Extensions in CHOICE types are properly marked as non-pointers
vlm4df9cc12005-03-09 22:19:25 +000064 (Test case 59) (Severity: medium, Security impact: medium)
vlm34dcd572005-01-17 11:40:49 +000065 Reported by <roman.pfender@sdm.de>.
vlmbd8d05f2005-01-17 12:35:57 +000066 * Tagged CHOICE type is now supported again.
67 (Test case 59) (Severity: low, Security impact: low)

vlmee5afb02004-10-02 15:55:20 +000082 * Enhanced UTF8String constraint validation, now it checks
83 for the minimal encoding length; API of UTF8String_length() changed.
vlm5cb31d52004-10-05 06:39:35 +000084 * Fixed SEQUENCE dealing with premature termination of the
85 optionals-laden indefinite length structure. The code was previously

vlm0d181f22004-09-29 13:30:32 +000096 * Added several security firewalls: decoder's stack usage control
97 and the stricter checking of the TLV length.
vlmf7ed1482004-09-22 16:06:52 +000098 * Implemented BASIC-XER encoding support (X.693).
vlm74e9e342004-09-24 21:06:19 +000099 * Implemented unber(1) and enber(1) for BER<->XML translation.
vlmf7ed1482004-09-22 16:06:52 +0000100 * Implemented CGI for online ASN.1 compilation (asn1c/webcgi).

vlm74e9e342004-09-24 21:06:19 +0000107 * Fixed BER decoder restartability problem with certain primitive
108 types (BOOLEAN, INTEGER, and REAL). The problem occured when the
109 encoding of such type is split between several bytes.
110 (Severity: high, Security impact: low)
vlm0d181f22004-09-29 13:30:32 +0000111 * Support for cross-referencing type definitions (updated ./tests/43-*).
vlmc8ee3052004-09-27 20:56:03 +0000112 * Fixed pretty-printing of the REAL type. Added lots of test cases.

vlmf72653e2004-09-13 08:32:15 +0000117
118 * Fixed CER (common BER) decoder code. See check-25.c/VisibleString
119 case for details. X.690 specifies that inner structures in BER
120 encoding must be tagged by stripping off the outer tag for each
121 subsequent containment level. See also X.690: 8.21.5.4 and
122 the "Spouse" case in A.3.
123 (Severity: medium, Security impact: low)

129 tagged CHOICE types. Fixed. Modified tests/37-indirect-choice-OK.asn1
vlmb47f48e2004-09-17 06:32:12 +0000130 * Improved type name generation code ("struct foo" vs "foo_t").
vlm9e4815d2004-09-15 12:01:04 +0000131 * Fixed constraint checking code incorrectly dealing with imported
132 types with constraint values defined in other modules.

vlmf0769b42004-07-15 10:52:58 +0000199
200 * Fixed parser: memory leak in free_struct code for SET OF/SEQUENCE OF.
201 (Severity: high, Security impact: medium)
vlmde1d8f72004-07-21 04:15:24 +0000202 * Fixed parser: invalid memory reference in code constructing tags.
vlm796c1da2004-07-21 03:55:44 +0000203 (Test case 48) (Severity: high, Security impact: medium)
204 When encoding data for certain ASN.1 specifications containing
205 explicit tags, the tag is always written incorrectly due to
206 incorrect memory reference. The encoding will almost always produce
207 unparseable data and might well reference unmapped region so program
208 would produce segmentation violation. Fortunately, memory is
209 read, not written, so remote exploits cannot execute arbitrary
210 code and triggering unmapped memory reference is highly unlikely
211 even it attacker knows the code (basically, the compiler should place
212 asn1_DEF_... right before the end of the mapped memory region, which
213 is extremely rare).
vlm7d278c42004-07-19 17:30:25 +0000214 * Improved INTEGER type printing.
vlmf0769b42004-07-15 10:52:58 +0000215
vlm79b08d52004-07-01 00:52:50 +00002160.8.14: 2004-Jun-30
217
218 * Fixed compiler: extensibility of CHOICE and SET type has not been
219 taken into account during table construction.
220 (Test case 47) (Severity: high, Security impact: low)
221
vlm65328a82004-06-28 21:22:20 +00002220.8.13: 2004-Jun-29
223
224 * Fixed compiler: the skip values for IMPLICIT tagging were broken
225 in some complex cases where one type is defined using another.
226 (Test case 46) (Severity: medium, Security impact: low).
227 * Added -fknown-extern-type command line parameter to asn1c.
228 * Removed -N command line flag and underlying functionality
229 to honor KISS principle.

234 anymore to an integer type of specific size (unsigned long). The
235 size of an integer must be provided explicitly.
236 See {OBJECT_IDENTIFIER|RELATIVE_OID}_{get|set}_arcs().

vlme511d3e2004-06-14 13:53:32 +0000243 * SEQUENCE BER decoder is now equipped with the sorted map
vlm45191f52004-06-06 07:20:37 +0000244 in case of complex CHOICE descendants. Test case 44 created.

250 structure.
251
2520.8.9: 2004-May-26
253
254 * Added *_{get|set}_arcs_*() functions for OBJECT IDENTIFIER
255 and RELATIVE-OID, together with test cases.
256
2570.8.8: 2004-May-09
258
259 * Introduced subtype constraints support (incomplete!).
260 * Fixed compiler. If the last member of the SEQUENCE is OPTIONAL
261 and absent in the encoding, and the type is extensible (...) or
262 EXTENSIBILITY IMPLIED flag is set, then the structure could not
263 be correctly decoded. (Severity: high, Security impact: low).
264 * Compiler: fixed recursive ASN.1 types inclusion (Severity: low,
265 Security impact: none).
266 * Parser: IMPORTS/FROM fixes, now allowing multiple sections.
vlm32d29a52004-10-26 10:44:18 +0000267 * NEW PLATFORM: Compiled and tested on MacOS X (@ PowerPC).
268 No major portability issues experienced.

2700.8.7: 2004-Apr-11 T-version-0-8-7
271
272 * Fixed SEQUENCE BER decoder: if the last member of the SEQUENCE is
273 OPTIONAL and absent in the encoding, RC_FAIL was returned instead
274 of RC_OK (Severity: high, Security impact: low).
275 * Added test case to check the above problem.
276 * Added test case to check -fnative-integers mode.
277

295 * Fixed SET::BER decoder: restart after reaching a buffer boundary
296 weas broken (Severity: blocker, Security impact: low).
297 * Fixed OCTET STRING::BER decoder: restart after reaching a buffer
298 boundary was broken (Severity: blocker, Security impact: low).
299 Reported by <vss@high.net.ru>
300 * Added test cases to check decoders restartability.
301 * Slightly more general INTEGER2long decoder.
302 * Allowed nested /* C-type */ comments, as per X.680:2002.
303
3040.8.2: 2004-Mar-01 T-version-0-8-2
305
306 * Fixed SEQUENCE BER decoder: an OPTIONAL element was required, where
307 should not have been (Severity: major; Security impact: low).
308 * Fixed print_struct pointer inheritance.
309 * Added -fno-c99 and -funnamed-unions
310
3110.8.1: 2004-Feb-22
312
313 * -R switch to asn1c: Omit support code, compile only the tables.
314 * Introduced NativeInteger pseudotype.
315 * Corrected the informal print_struct()'s output format.
316
3170.8.0: 2004-Feb-03 T-version-0-8-0
318
319 * Some documentation is created (a .pdf and a short manual page).
320 * Last touches to the code.
321
3220.7.9: 2004-Feb-01 T-version-0-7-9

325 * Support for implicit (standard) constraints.
326
3270.7.8: 2004-Jan-31
328
329 * SET now rejects duplicate fields in the data stream.
330
3310.7.7: 2004-Jan-25
332
333 * Added types: GeneralizedTime and UTCTime.
334
3350.7.6: 2004-Jan-24 T-version-0-7-6
336
337 * DER encoding of a SET OF now involves dynamic sorting.
338
3390.7.5: 2004-Jan-24 T-version-0-7-5
340
341 * DER encoding of a SET with untagged CHOICE
342 now involves dynamic sorting.
343
3440.7.0: 2004-Jan-19 T-version-0-7-0
345
346 * A bunch of DER encoders is implemented.
347

376=== Bug importance disclosure terms ===
377
378SEVERITY.
379 This term applies to the frequence the particular construct is used
380 in the real world. The higher the frequency, the more chances of triggering
381 this bug.
382 low: The ASN.1 specifications which could trigger
383 this kind of bug are not widespread.
384 medium: The particular ASN.1 construct is used quite often,
385 so the chance of triggering an error is considerable.
386 high: This fix is considered urgent, or the particular ASN.1
387 construct triggering this bug is in wide use.
388
389SECURITY IMPACT.
390 This term applies to the amount of potential damage a bug exploitation
391 could cause.
392 low: The local exploitation is unlikely; the remote exploitation
393 is impossible.
394 medium: The remote exploitation is possible when a particular ASN.1
395 construct is being used. If possible, only hard failure, spin
396 or memory leak are the possible outcome: no shellcode
397 injection could possibly be carried by the attack.
398 high: The remote shellcode injection is possible, or the bug is
399 otherwise remotely exploitable for most specifications.
