1GNU Libtasn1 NEWS -*- outline -*- 2 3* Noteworthy changes in release 4.18.0 (2021-11-09) [stable] 4- Improve GTK-DOC manual. Closes: #35. 5- Improve --help and --version for tools with gnulib. Closes: #37. 6- Update gnulib files and various maintenance fixes. 7 8* Noteworthy changes in release 4.17.0 (2021-05-13) [stable] 9- Print deprecation messages for deprecated macros, thanks to Tim Rühsen. 10- Fix some clang issues due to illegal pointers, thanks to Stefan Weil. 11- Restore handling of SIZE nodes, thanks to Dmitry Baryshkov. 12- Fix memory leak caught by oss-fuzz, thanks to Dmitry Baryshkov. 13- Gtk-doc fixes, thanks to Dmitry Baryshkov. 14- Fix bugs unveiled by Static Analysis, reported by Simo Sorce. 15- Update gnulib files and many build fixes. 16 17* Noteworthy changes in release 4.16.0 (released 2020-02-01) [stable] 18- asn1_decode_simple_ber: added support for constructed definite 19 octet strings. This allows this function decode the whole set of 20 BER encodings for OCTET STRINGs. 21- asn1_get_object_id_der: enhance the range of decoded OIDs (#25). 22 This also makes OID encoding and decoding more strict on invalid 23 input. This may break gnutls' test suite before 3.6.12 as it was 24 relying on decoding some invalid OIDs. 25- asn1_object_id_der: New function 26 27 28* Noteworthy changes in release 4.15.0 (released 2019-11-21) [stable] 29- The generated tree no longer contains ASN.1 built-in types even 30 if they are explicitly defined in the description. Previously 31 a warning was printed when these types were seen, now they are 32 ignored. 33- Several fixes in ASN.1 definition parser, preventing several 34 crashes and leaks in the tools due to improper ASN.1. 35- Switched to semantic versioning. 36 37 38* Noteworthy changes in release 4.14 (released 2019-07-21) [stable] 39- New #defines for version checking: ASN1_VERSION_MAJOR, ASN1_VERSION_MINOR, 40 ASN1_VERSION_PATCH, ASN1_VERSION_NUMBER. The next release will switch 41 to semantic version semantics. 42- Simplify ordering of SET OF elements by using qsort(). 43- Marked explicitly const uses of asn1_node with the introduction 44 of the (compatible) asn1_node_const type. 45- Limit recursion in _asn1_expand_object_id() to detect infinite 46 recursion in incorrect .asn files (#4). 47- asn1_array2tree(): fixed thread safety issues. 48- Several fixes in gtk-doc generation. 49 50 51* Noteworthy changes in release 4.13 (released 2018-01-16) [stable] 52- On indefinite string decoding, set a maximum level of allowed recursions 53 (3) to protect the BER decoder from a stack exhaustion. 54 55* Noteworthy changes in release 4.12 (released 2017-05-29) [stable] 56- Corrected so-name version 57 58* Noteworthy changes in release 4.11 (released 2017-05-27) [stable] 59- Introduced the ASN1_TIME_ENCODING_ERROR error code to indicate 60 an invalid encoding in the DER time fields. 61- Introduced flag ASN1_DECODE_FLAG_ALLOW_INCORRECT_TIME. This flag 62 allows decoding errors in time fields even when in strict DER mode. 63 That is introduced in order to allow toleration of invalid times in 64 X.509 certificates (which are common) even though strict DER adherence 65 is enforced in other fields. 66- Added safety check in asn1_find_node(). That prevents a crash 67 when a very long variable name is provided by the developer. 68 Note that this to be exploited requires controlling the ASN.1 69 definitions used by the developer, i.e., the 'name' parameter of 70 asn1_write_value() or asn1_read_value(). The library is 71 not designed to protect against malicious manipulation of the 72 developer assigned variable names. Reported by Jakub Jirasek. 73 74* Noteworthy changes in release 4.10 (released 2017-01-16) [stable] 75- Updated gnulib 76- Removed -Werror from default compiler flags 77- Fixed undefined behavior when negating integers in _asn1_ltostr(). 78 Issue found by oss-fuzz project (via gnutls): 79 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=388 80- Pass the correct length to _asn1_get_indefinite_length_string in 81 asn1_get_length_ber. This addresses reading 1-byte past the end 82 of data. Issue found by oss-fuzz project (via gnutls): 83 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=330 84 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=331 85 86* Noteworthy changes in release 4.9 (released 2016-07-25) [stable] 87- Fixes to OID encoding of OIDs which have elements which exceed 2^32 88 89* Noteworthy changes in release 4.8 (released 2016-04-11) [stable] 90- Fixes to avoid reliance on C undefined behavior. 91- Fixes to avoid an infinite recursion when decoding without 92 the ASN1_DECODE_FLAG_STRICT_DER flag. Reported by Pascal Cuoq. 93- Combined all the BER octet string decoding functions to a single 94 one based on asn1_decode_simple_ber(). 95 96* Noteworthy changes in release 4.7 (released 2015-09-14) [stable] 97- Fixed regression introduced in the decoding of multi-byte tags 98 fix. 99 100* Noteworthy changes in release 4.6 (released 2015-09-05) [stable] 101- Allow decoding OCTET STRINGs with multi-byte tags. 102- API and ABI changes since last version: 103 asn1_get_object_id_der: New function 104 105* Noteworthy changes in release 4.5 (released 2015-04-29) [stable] 106- Corrected an invalid memory access in octet string decoding. 107 Reported by Hanno Böck. 108 109* Noteworthy changes in release 4.4 (released 2015-03-29) [stable] 110- Corrected a two-byte stack overflow in asn1_der_decoding. Reported 111 by Hanno Böck. 112 113* Noteworthy changes in release 4.3 (released 2015-03-09) [stable] 114- Added asn1_decode_simple_ber() 115 116* Noteworthy changes in release 4.2 (released 2014-09-15) [stable] 117- Added sanity checks in the decoding of time when 118 ASN1_DECODE_FLAG_STRICT_DER is used. 119- Fixes in the decoding of OCTET STRING when close to the end 120 of the structure. 121 122* Noteworthy changes in release 4.1 (released 2014-08-23) [stable] 123- Corrected indefinite tag check in ANY constructions. That allows 124 the decoding of BER-encoded structures that contain indefinite 125 encoding within an ANY element. 126- Added DER decoding flag ASN1_DECODE_FLAG_STRICT_DER. Over the 127 years BER functionality was added to the decoder and this flag 128 provides the way to disable it. 129- API and ABI changes since last version: 130 ASN1_DECODE_FLAG_STRICT_DER: New definition 131 132* Noteworthy changes in release 4.0 (released 2014-06-26) [stable] 133- Optimized asn1_der_decoding_startEnd(). It no longer requires the 134 additional decoding step. 135- asn1_read_value() understands the ?CURRENT keyword, which can be used 136 to indicate the current element of a sequence, when the provided node 137 is a sequence element. 138- Several optimizations in DER decoding of structures with sequences 139 containing many elements. 140- asn1_der_decoding2() is introduced and allows flags to be passed on 141 the decoding process. Currently only ASN1_DECODE_FLAG_ALLOW_PADDING is 142 defined and that allows decoding DER structures that contain arbitrary 143 data past their end. Contributed by Karel Slany. 144- API and ABI changes since last version: 145 ASN1_DECODE_FLAG_ALLOW_PADDING: New definition 146 asn1_dup_node: New function 147 asn1_der_decoding2: New function 148 asn1_der_decoding_element: It is now an alias to asn1_der_decoding 149 150* Noteworthy changes in release 3.6 (released 2014-05-25) [stable] 151- Corrected an off-by-one error in ASN.1 DER tag decoding. 152- Several improvements and new safety checks on DER decoding; 153 issues found using Codenomicon TLS test suite. 154- Marked asn1_der_decoding_element() as deprecated. Use 155 asn1_der_decoding() instead. 156 157* Noteworthy changes in release 3.5 (released 2014-05-01) [stable] 158- Correctly handle decoding of recursive CHOICE options. 159- Allow deleting elements of SET OF.
