0.9.20: 2006-Mar-06
|
|
|
|
* SET OF CHOICE, SEQUENCE OF CHOICE and a certain named S/O types

(Test case 70) (Severity: low; Security impact: low)
|
|
* asn1c: Removed -ftypes88 command line option.
|
|
* Started PER implementation. Somewhat experimental!
|
|
|
|
0.9.19: 2005-Oct-06
|
|
|
|
* A proper solution to circular references. No kludge flags
|
|
should be necessary anymore to produce reference-free code:

|
|
* Generating enumeration tables for BIT STRING types (Test case 89).
|

|
type is chosen based on PER visible constraints (Test cases 90, 91).
|
|
* Union structures for CHOICE type are not anonymous anymore.
|
|
* Made unber(1) program more verbose: effective structure length is
|
|
now displayed as L="<n>" at the closing tag. (Test check-xxber.sh).

|
|
|
|

|
|
|
|
* Fixed check-70.-fnative-integers.c test (it was failing

|
|
|
|
* Added extra const qualifiers into the support code.
|
|

|
|
clash with system's <time.h> on a Win32 system).
|
|
* Small refinement of XML DTD generation (`asn1c -X`).
|
|
* Relaxed XER processing rules to skip extra whitespace
|
|
in some more places. It also skips XML comments (although
|
|
XML comments in XER are prohibited by X.693, #8.2.1).
|
|
(Test case 70) (Severity: medium; Security impact: none)
|
|
Reported by <Dominique.Nerriec@alcatel.fr>.
|

|
|
|
|

|
|
|
|
* Released -fcompound-names to fix the name clashes in the code
|
|
produced by the asn1c.
|

|
|
* Compiler is taught to produce compilable code for yet another class

|
of circular ASN.1 type references.
|
|
* X.693:8.3.4 prohibits anything but SignedNumber; fixed XER codec.
|
|
* Fixed ENUMERATED identifier to value conversion in XER.
|
|
Reported by <jacque.celaire@caramail.com>.
|
|
* If the compiled file contents are the same as in already existing
|
|
file (left from previous compilation), the old file is retained.
|
|
This prevents thrashing `make` dependencies if amount of changes in
|
|
the original ASN.1 module(s) is small.
|
|
|
|
0.9.10: 2005-Feb-25
|
|
|
|
* Completed the XER XMLValueList encoding and decoding.

|
|
experimental).
|

|
|
|
|
0.9.8: 2005-Jan-17
|
|
|
|
* [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!
|
|
* [NEW PLATFORM] Compiled and tested on Sun Solaris 9 @ sparc.
|
|
Improved includes/defines of/for system headers.
|
|

|
|
identifiers (./tests/68-*-OK.asn1).
|
|
* ber_dec_rval_t renamed into asn_dec_rval_t: more generality.
|
|
* Extensions in CHOICE types are properly marked as non-pointers
|
|
(Test case 59) (Severity: medium; Security impact: medium)
|
|
Reported by <roman.pfender@sdm.de>.
|
|

|
|
ordering support.
|
|
* Fixed unber(1) limits controlling logic.
|
|
* Removed C99'izm from the x509dump, now understood by older compilers.
|
|
* Enhanced UTF8String constraint validation, now it checks
|
|
for the minimal encoding length; API of UTF8String_length() changed.
|
|
* Fixed SEQUENCE dealing with premature termination of the
|
|
optionals-laden indefinite length structure. The code was previously
|
|
refusing to parse such structures.
|
|
* Fixed explicitly tagged ANY type encoding and decoding
|
|
(Severity: medium; Security impact: low).
|
|
* Fixed CHOICE code spin when indefinite length structures appear
|
|
in the extensions (Severity: medium; Security impact: medium).
|
|
Reported by <siden@ul-gsm.ru>.
|
|
* BIT STRING now stores the number of unused octets in a separate field.
|
|
|
|
0.9.6: 2004-Sep-29
|
|
|
|
* Added several security firewalls: decoder's stack usage control
|
|
and the stricter checking of the TLV length.
|
|
* Implemented BASIC-XER encoding support (X.693).
|
|
* Implemented unber(1) and enber(1) for BER<->XML translation.
|
|
* Implemented CGI for online ASN.1 compilation (asn1c/webcgi).
|
|
* Implemented the sample X.509 decoder (./examples/sample.source.PKIX1).
|
|
* NamedType is now supported for SET OF/SEQUENCE OF type.
|
|
* Added -fno-constraints option to asn1c, which disabled generation of
|
|
ASN.1 subtype constraints checking code.
|
|
* Added ASN1C_ENVIRONMENT_VERSION and get_asn1c_environment_version().
|
|
* Fixed ANY type decoding (Severity: high; Security impact: low).
|
|
* Fixed BER decoder restartability problem with certain primitive
|
|
types (BOOLEAN, INTEGER, and REAL). The problem occured when the
|
|
encoding of such type is split between several bytes.
|
|
(Severity: high; Security impact: low)
|
|
* Support for cross-referencing type definitions (updated ./tests/43-*).

|
|
|
|
* Fixed CER (common BER) decoder code. See check-25.c/VisibleString
|
|
case for details. X.690 specifies that inner structures in BER
|
|
encoding must be tagged by stripping off the outer tag for each
|
|
subsequent containment level. See also X.690: 8.21.5.4 and
|
|
the "Spouse" case in A.3.
|

|
|
* Fixed constraint checking code incorrectly dealing with imported
|
|
types with constraint values defined in other modules.
|
|
* Real REAL support! (Haven't tested denormals support yet!)
|
|
See skeletons/tests/check-REAL.c
|
|
|
|

|
|
|
* More support for recursive type definitions.
|
|

|
PER visibility rules for actual constraints checking code generator.
|
|

|
|
* Fixed OBJECT IDENTIFIER human-readable printing.
|
|
Reported by <siden@ul-gsm.ru>.
|
|
|
|

|
|
|
|
* Reworked subtype constraints handling, aiming at PER-applicability.
|
|
* BOOLEAN and NULL are now implemented in terms of native int type.
|
|

|
|
* Added support COMPONENTS OF construct.
|
|
* Numerous parser fixes and enhancements.
|
|
* Better constraint failure reporting.
|
|
|
|
0.8.19: 2004-Aug-18
|
|
|
|
* Fixed BER encoder (problem encoding large tag values)
|
|
(Severity: medium; Security impact: low)
|
|
|
|
0.8.18: 2004-Aug-12

|
|
|
* Parser: fixed multiple IMPORTS problem (incorrect assertion).
|
|
* Parser: constraints extensibility parsing fix.
|
|
|
|
0.8.17: 2004-Aug-11
|
|
|
|
* Improved compiler output: duplicate #includes eliminated.
|
|
* Win32 portability fixes.
|
|
* More compatibility with C++ or non-GCC compilers.
|
|
|
|
0.8.16: 2004-Jul-22
|
|
|
|
* Fixed application-level problem in SET OF/SEQUENCE OF array cleanup.
|
|
(Severity: medium; Security impact: low)
|
|
* Improved asn_GT2time() and added asn_time2{GT,UT}() functions.
|
|
* BIT STRING pretty-printing.
|
|
|
|
0.8.15: 2004-Jul-20
|
|
|
|
* Fixed parser: memory leak in free_struct code for SET OF/SEQUENCE OF.
|
|
(Severity: high; Security impact: medium)
|
|
* Fixed parser: invalid memory reference in code constructing tags.
|
|
(Test case 48) (Severity: high; Security impact: medium)
|
|
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).
|
|
* Improved INTEGER type printing.
|
|
|
|
0.8.14: 2004-Jun-30
|
|
|
|
* Fixed compiler: extensibility of CHOICE and SET type has not been
|
|
taken into account during table construction.
|
|
(Test case 47) (Severity: high; Security impact: low)
|
|
|
|
0.8.13: 2004-Jun-29
|
|
|
|
* Fixed compiler: the skip values for IMPLICIT tagging were broken
|
|
in some complex cases where one type is defined using another.
|
|
(Test case 46) (Severity: medium; Security impact: low).
|
|
* Added -fknown-extern-type command line parameter to asn1c.
|
|
* Removed -N command line flag and underlying functionality
|
|
to honor KISS principle.
|
|
|
|
0.8.12: 2004-Jun-17
|
|
|
|
* RELATIVE-OID and OBJECT IDENTIFIER encoders/decoders are not bound
|
|
anymore to an integer type of specific size (unsigned long). The
|
|
size of an integer must be provided explicitly.
|
|
See {OBJECT_IDENTIFIER|RELATIVE_OID}_{get|set}_arcs().
|
|
* SEQUENCE BER decoder fixed again for complex CHOICE case
|
|
(Test case 44) (Severity: medium; Security impact: low).
|
|
|
|
0.8.11: 2004-Jun-05
|
|
|
|
* Enforced stricter conformance with C standards.
|
|
* SEQUENCE BER decoder is now equipped with the sorted map
|
|
in case of complex CHOICE descendants. Test case 44 created.
|
|
|
|
0.8.10: 2004-Jun-02
|
|
|
|
* Added const qualifier where necessary.
|
|
* Changed position of outmost_tag fetcher within asn1_TYPE_descriptor_t
|
|
structure.
|
|
|
|
0.8.9: 2004-May-26
|
|
|
|
* Added *_{get|set}_arcs_*() functions for OBJECT IDENTIFIER
|
|
and RELATIVE-OID, together with test cases.
|
|
|
|
0.8.8: 2004-May-09
|
|
|
|
* Introduced subtype constraints support (incomplete!).
|
|
* Fixed compiler. If the last member of the SEQUENCE is OPTIONAL
|
|
and absent in the encoding, and the type is extensible (...) or
|
|
EXTENSIBILITY IMPLIED flag is set, then the structure could not
|
|
be correctly decoded. (Severity: high; Security impact: low).
|
|
* Compiler: fixed recursive ASN.1 types inclusion (Severity: low,
|
|
Security impact: none).

0.8.7: 2004-Apr-11 T-version-0-8-7
|
|
|
|

|
|
OPTIONAL and absent in the encoding, RC_FAIL was returned instead
|
|
of RC_OK (Severity: high; Security impact: low).

|
|
|
|
0.8.4: 2004-Mar-22
|
|

|
|
boundary was broken (Severity: high; Security impact: low).

Reported by <vss@high.net.ru>
|
|
* Added test cases to check decoders restartability.
|
|
* Slightly more general INTEGER2long decoder.

|
|
|
|
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.
|
|
|
|

=== 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.
|
|
none: No malicious exploitation is possible.
|
|
low: The local exploitation is unlikely; the remote exploitation
|
|
is not possible.
|
|
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.
