vlm6d44a542005-11-08 03:06:16 +00003
4 * SET OF CHOICE, SEQUENCE OF CHOICE and a certain named S/O types
5 are represented differently in XER. THIS IS AN ICOMPATIBLE CHANGE.
6 (Test case 70) (Severity: low; Security impact: low)
vlm337167e2005-11-26 11:25:14 +00007 * asn1c: Removed -ftypes88 command line option.
vlm0bea9192006-03-06 10:10:28 +00008 * Started PER implementation. Somewhat experimental!

vlm6c4a8502005-08-18 13:38:19 +000012 * A proper solution to circular references. No kludge flags
13 should be necessary anymore to produce reference-free code:
14 recursive dependencies are resolved automatically.
vlm5a6fc652005-08-16 17:00:21 +000015 * Test cases 73 & 92 keep track of various circular references.
vlm177a5b62005-09-05 05:17:57 +000016 * Introduced compiler directives to allow finer control over the
17 generated code ("--<ASN1C...>--" in comments), (Test case 93).

vlm5d89c3d2005-08-13 09:07:11 +000025 * The obsolete X.208 syntax is handled gracefully now (compound types'
26 member names are invented on the fly). (Test case 87).
vlm4573af02005-08-13 23:30:24 +000027 * Generating enumeration tables for INTEGER types (Test case 88).
vlm96853d82005-08-13 23:51:47 +000028 * Generating enumeration tables for BIT STRING types (Test case 89).
vlm75b3a532005-08-14 02:18:27 +000029 * Conditional INTEGER/ENUMERATED representation: long vs. INTEGER_t
vlm27028582005-08-14 14:45:44 +000030 type is chosen based on PER visible constraints (Test cases 90, 91).
vlm2e774282005-08-14 15:03:31 +000031 * Union structures for CHOICE type are not anonymous anymore.
vlme0297112005-08-15 03:28:06 +000032 * Made unber(1) program more verbose: effective structure length is
33 now displayed as L="<n>" at the closing tag. (Test check-xxber.sh).
34 * Fixed unber(1)'s -1 switch for indefinite encoding length.
vlm1f137432005-08-15 07:21:22 +000035 * New command line option for unber(1): -m to enable minimalistic mode.
vlm131ba382005-08-12 05:13:35 +000036

39 * Tagging mode is implicitly IMPLICIT if AUTOMATIC TAGS is used, #30.6.
40 (Test cases 55, 86).
vlm3a417582005-07-24 09:03:44 +000041 * Started to use extern "C" {} in skeleton headers.
42 * Introduced -finline-choice command line option to fix
43 yet another class of circular references.

48 Thanks to Bent Nicolaisen <BN@JAI.com> for support.
vlmb5abdc92005-07-02 21:42:40 +000049 * ASN.1 parser has been tweaked to allow parsing something like
vlm754a90f2005-07-04 02:03:57 +000050 "SEQUENCE----comment----", which is ambiguous for many reasons.
vlm50f0a172005-07-03 05:32:55 +000051 * XER decoder better handles not-yet-defined future extensions.
vlmb5abdc92005-07-02 21:42:40 +000052
vlm67b528d2005-07-02 08:19:26 +0000530.9.15: 2005-July-02
vlme6c89732005-05-17 21:46:18 +000054
55 * Compiler now checks 64-bit overflows in constraints range handling
56 code. No effect on the code produced by the compiler.
vlm1457c0d2005-06-02 17:53:17 +000057 * Compiler support for tagged and marked parametrized members.

83 * Fixed a name clash in produced constraint checking code.
vlm24b7eb12005-03-06 09:31:59 +000084 * #includes are now in single quotes (to solve a name
85 clash with system's <time.h> on a Win32 system).
vlm4df9cc12005-03-09 22:19:25 +000086 * Small refinement of XML DTD generation (`asn1c -X`).
87 * Relaxed XER processing rules to skip extra whitespace
88 in some more places. It also skips XML comments (although
vlmbe7a5322005-03-10 11:50:12 +000089 XML comments in XER are prohibited by X.693, #8.2.1).
vlm82abba82005-04-25 19:38:21 +000090 (Test case 70) (Severity: medium; Security impact: none)
vlm4df9cc12005-03-09 22:19:25 +000091 Reported by <Dominique.Nerriec@alcatel.fr>.

vlm560eeb82005-03-04 11:20:17 +0000108 Reported by <jacque.celaire@caramail.com>.
vlm4fff94d2005-03-04 09:01:15 +0000109 * If the compiled file contents are the same as in already existing
110 file (left from previous compilation), the old file is retained.
111 This prevents thrashing `make` dependencies if amount of changes in
112 the original ASN.1 module(s) is small.
vlmdca48302005-03-03 21:29:10 +0000113

126 Reported by <mikko.ahonen@elma.net>.
vlm62a14752005-01-23 09:51:53 +0000127 * Fixed tag parsing (tags like "[ 0 ]" were not supported).
vlmd7f47c02005-02-22 08:14:24 +0000128 * Compiler now checks for duplicate ASN.1 types across modules.
vlm54af01c2005-01-17 15:27:47 +0000129
vlm34dcd572005-01-17 11:40:49 +00001300.9.8: 2005-Jan-17

vlm32d29a52004-10-26 10:44:18 +0000132 * [NEW PLATFORM] Compiled and tested on Linux @ alpha64 (LP64).
133 Some code needed to be fixed regarding int-long conversions
134 (mostly inside the test suite), and floating point handling
135 code needed to be restructured to handle signalling NAN and
136 other floating point exceptions quietly. Smooth transition!
137 * [NEW PLATFORM] Compiled and tested on Sun Solaris 9 @ sparc.
138 Improved includes/defines of/for system headers.
vlm60e7ef02004-10-13 09:13:56 +0000139 * -X command line option added to asn1c to generate XML DTD.

vlmee5afb02004-10-02 15:55:20 +0000164 * Enhanced UTF8String constraint validation, now it checks
165 for the minimal encoding length; API of UTF8String_length() changed.
vlm5cb31d52004-10-05 06:39:35 +0000166 * Fixed SEQUENCE dealing with premature termination of the
167 optionals-laden indefinite length structure. The code was previously
168 refusing to parse such structures.
vlm267b7fd2004-10-11 11:43:08 +0000169 * Fixed explicitly tagged ANY type encoding and decoding
vlm82abba82005-04-25 19:38:21 +0000170 (Severity: medium; Security impact: low).

vlm0d181f22004-09-29 13:30:32 +0000178 * Added several security firewalls: decoder's stack usage control
179 and the stricter checking of the TLV length.
vlmf7ed1482004-09-22 16:06:52 +0000180 * Implemented BASIC-XER encoding support (X.693).
vlm74e9e342004-09-24 21:06:19 +0000181 * Implemented unber(1) and enber(1) for BER<->XML translation.

vlm74e9e342004-09-24 21:06:19 +0000183 * Implemented the sample X.509 decoder (./examples/sample.source.PKIX1).
vlmf7ed1482004-09-22 16:06:52 +0000184 * NamedType is now supported for SET OF/SEQUENCE OF type.
vlm986afd62004-09-26 13:16:56 +0000185 * Added -fno-constraints option to asn1c, which disabled generation of
186 ASN.1 subtype constraints checking code.
vlmf7ed1482004-09-22 16:06:52 +0000187 * Added ASN1C_ENVIRONMENT_VERSION and get_asn1c_environment_version().
vlm82abba82005-04-25 19:38:21 +0000188 * Fixed ANY type decoding (Severity: high; Security impact: low).
vlm74e9e342004-09-24 21:06:19 +0000189 * Fixed BER decoder restartability problem with certain primitive
190 types (BOOLEAN, INTEGER, and REAL). The problem occured when the
191 encoding of such type is split between several bytes.
vlm82abba82005-04-25 19:38:21 +0000192 (Severity: high; Security impact: low)
vlm0d181f22004-09-29 13:30:32 +0000193 * Support for cross-referencing type definitions (updated ./tests/43-*).

vlmf72653e2004-09-13 08:32:15 +0000199
200 * Fixed CER (common BER) decoder code. See check-25.c/VisibleString
201 case for details. X.690 specifies that inner structures in BER
202 encoding must be tagged by stripping off the outer tag for each
203 subsequent containment level. See also X.690: 8.21.5.4 and
204 the "Spouse" case in A.3.
vlm82abba82005-04-25 19:38:21 +0000205 (Severity: medium; Security impact: low)

211 tagged CHOICE types. Fixed. Modified tests/37-indirect-choice-OK.asn1
vlmb47f48e2004-09-17 06:32:12 +0000212 * Improved type name generation code ("struct foo" vs "foo_t").
vlm9e4815d2004-09-15 12:01:04 +0000213 * Fixed constraint checking code incorrectly dealing with imported
214 types with constraint values defined in other modules.

282 * Fixed parser: memory leak in free_struct code for SET OF/SEQUENCE OF.
vlm82abba82005-04-25 19:38:21 +0000283 (Severity: high; Security impact: medium)
vlmde1d8f72004-07-21 04:15:24 +0000284 * Fixed parser: invalid memory reference in code constructing tags.
vlm82abba82005-04-25 19:38:21 +0000285 (Test case 48) (Severity: high; Security impact: medium)
vlm796c1da2004-07-21 03:55:44 +0000286 When encoding data for certain ASN.1 specifications containing
287 explicit tags, the tag is always written incorrectly due to
288 incorrect memory reference. The encoding will almost always produce
289 unparseable data and might well reference unmapped region so program
290 would produce segmentation violation. Fortunately, memory is
291 read, not written, so remote exploits cannot execute arbitrary
292 code and triggering unmapped memory reference is highly unlikely
293 even it attacker knows the code (basically, the compiler should place
294 asn1_DEF_... right before the end of the mapped memory region, which
295 is extremely rare).
vlm7d278c42004-07-19 17:30:25 +0000296 * Improved INTEGER type printing.
vlmf0769b42004-07-15 10:52:58 +0000297
vlm79b08d52004-07-01 00:52:50 +00002980.8.14: 2004-Jun-30

305
306 * Fixed compiler: the skip values for IMPLICIT tagging were broken
307 in some complex cases where one type is defined using another.
vlm82abba82005-04-25 19:38:21 +0000308 (Test case 46) (Severity: medium; Security impact: low).
vlm65328a82004-06-28 21:22:20 +0000309 * Added -fknown-extern-type command line parameter to asn1c.

316 anymore to an integer type of specific size (unsigned long). The
317 size of an integer must be provided explicitly.
318 See {OBJECT_IDENTIFIER|RELATIVE_OID}_{get|set}_arcs().
vlme511d3e2004-06-14 13:53:32 +0000319 * SEQUENCE BER decoder fixed again for complex CHOICE case
vlm82abba82005-04-25 19:38:21 +0000320 (Test case 44) (Severity: medium; Security impact: low).
vlme511d3e2004-06-14 13:53:32 +0000321

338
3390.8.8: 2004-May-09
340
341 * Introduced subtype constraints support (incomplete!).
342 * Fixed compiler. If the last member of the SEQUENCE is OPTIONAL
343 and absent in the encoding, and the type is extensible (...) or
344 EXTENSIBILITY IMPLIED flag is set, then the structure could not
vlm82abba82005-04-25 19:38:21 +0000345 be correctly decoded. (Severity: high; Security impact: low).
vlmfa67ddc2004-06-03 03:38:44 +0000346 * Compiler: fixed recursive ASN.1 types inclusion (Severity: low,
347 Security impact: none).
348 * Parser: IMPORTS/FROM fixes, now allowing multiple sections.
vlm32d29a52004-10-26 10:44:18 +0000349 * NEW PLATFORM: Compiled and tested on MacOS X (@ PowerPC).
350 No major portability issues experienced.
vlmfa67ddc2004-06-03 03:38:44 +0000351
3520.8.7: 2004-Apr-11 T-version-0-8-7
353
354 * Fixed SEQUENCE BER decoder: if the last member of the SEQUENCE is
355 OPTIONAL and absent in the encoding, RC_FAIL was returned instead
vlm82abba82005-04-25 19:38:21 +0000356 of RC_OK (Severity: high; Security impact: low).
vlmfa67ddc2004-06-03 03:38:44 +0000357 * Added test case to check the above problem.

458=== Bug importance disclosure terms ===
459
460SEVERITY.
461 This term applies to the frequence the particular construct is used
462 in the real world. The higher the frequency, the more chances of triggering
463 this bug.
464 low: The ASN.1 specifications which could trigger
465 this kind of bug are not widespread.
466 medium: The particular ASN.1 construct is used quite often,
467 so the chance of triggering an error is considerable.
468 high: This fix is considered urgent, or the particular ASN.1
469 construct triggering this bug is in wide use.
470
471SECURITY IMPACT.
472 This term applies to the amount of potential damage a bug exploitation
473 could cause.
474 low: The local exploitation is unlikely; the remote exploitation
475 is impossible.
476 medium: The remote exploitation is possible when a particular ASN.1
477 construct is being used. If possible, only hard failure, spin
478 or memory leak are the possible outcome: no shellcode
479 injection could possibly be carried by the attack.
480 high: The remote shellcode injection is possible, or the bug is
481 otherwise remotely exploitable for most specifications.
482
