|
|
9 | - SECURITY FIX: fix two bugs found by american fuzzy lop, |
|
|
10 | upgrade is advised if you accept data from untrusted |
|
|
11 | sources. |
|
|
12 | - an out-of bound sharedref or stringref index could cause an |
|
|
13 | out of bounds access - might be exploitable. |
|
|
14 | - a decoding error during indefinite array or hash decoding |
|
|
15 | could cause an endless loop. |
|
|
16 | |
|
|
17 | 1.6 Wed Dec 7 15:13:23 CET 2016 |
|
|
18 | - greatly expand the SECURITY IMPLICATIONS and similar sections. |
|
|
19 | - new constructor new_safe, to create a secure CBOR::XS object. |
|
|
20 | - new option forbid_objects, to disallow serialisation. |
|
|
21 | - new CBOR::XS::safe_filter functionality. |
|
|
22 | - fix a crash when decoding a cyclic data structure using |
|
|
23 | stringref/pack_strings when allow_cycles is disabled. |
|
|
24 | - fix a crash when decoding hash keys with length >= 2**31. |
|
|
25 | - avoid unreasonably long decoding times for certain |
|
|
26 | types of (corrupt) cbor texts. |
|
|
27 | - support arrays and hashes with >= 2**31 members. |
|
|
28 | - avoid overflow on pointer arithmetic when checking whether enough |
|
|
29 | data is available. |
|
|
30 | - fix a memory leak that occured when decoding failed while decoding |
|
|
31 | a tagged value. |
|
|
32 | - do not leak the partially constructed result when stringifying |
|
|
33 | a hash key throws an exception. |
|
|
34 | - various code size and efficiency optimizations (reduced code |
|
|
35 | from 42 to 40kB on my system, despite the new features). |
|
|
36 | |
|
|
37 | 1.5 Wed Apr 27 11:38:39 CEST 2016 |
|
|
38 | - Math::BigFloat madness workaround, see |
|
|
39 | http://blog.schmorp.de/2016-04-23-mathbigfloat-maintainer-fail.html |
|
|
40 | (bugreport by zdm@softvisio.net). |
|
|
41 | - add text_keys and text_strings options to force CBOR text encoding |
|
|
42 | for perl hash keys or all strings, as a result of discussions |
|
|
43 | with Fredrik Ljunggren. |
|
|
44 | - implement support for arbitrary-exponent numbers (see |
|
|
45 | http://peteroupc.github.io/CBOR/bigfrac.html, tags 264 and 265) |
|
|
46 | for both en- and decoding. |
|
|
47 | - implement support for rational numbers (see |
|
|
48 | http://peteroupc.github.io/CBOR/rational.html, tag 30) for both |
|
|
49 | en- and decoding. |
|
|
50 | - the above effectively implements all registered CBOR extensions |
|
|
51 | in a sensible manner. |
|
|
52 | - remove some weird dead code that was duplicated (%FILTER). |
|
|
53 | - add t/58_hv.t, which tests hashes and the new text_* flags. |
|
|
54 | hashes apparently were not encoded at all in any of the existing |
|
|
55 | tests. |
|
|
56 | - document Math::BigFloat base-2 performance/crash issues. |
|
|
57 | - use stability canary. |
|
|
58 | |
|
|
59 | 1.41 Thu 25 Feb 15:22:03 CET 2016 |
|
|
60 | - avoid perl panics on nested FREEZE/THAW calls (testcase by |
|
|
61 | Victor Efimov). |
|
|
62 | |
|
|
63 | 1.4 Mon Feb 8 05:10:15 CET 2016 |
|
|
64 | - buffer overflow fix: a fast path during decoding did not check |
|
|
65 | remaining length when decoding hash keys, found by fuzzing. |
|
|
66 | This can potentially leak information in the error message |
|
|
67 | or crash the process. |
|
|
68 | - use C style { 0 } struct initializer. |
|
|
69 | - upgrade libecb. |
|
|
70 | |
|
|
71 | 1.3 Mon Apr 27 22:21:04 CEST 2015 |
|
|
72 | - the incremental parser didn't properly parse tagged values |
|
|
73 | (testcase by Mons Anderson). |
|
|
74 | - slightly speed up encoding of plain (nonmagical) arrays. |
|
|
75 | - try to clarify further that effectively all 32 bit architectures |
|
|
76 | have 64 bit integer support. |
|
|
77 | - upgrade libecb. |
|
|
78 | |
|
|
79 | 1.26 Sat Oct 25 08:35:44 CEST 2014 |
|
|
80 | - update the t/57_incr.t subtest that would rely on 64 bit ints. |
|
|
81 | - disable t/50_rfc.t test that fails because of broken data::dumper. |
|
|
82 | |
|
|
83 | 1.25 Sun Jan 5 15:19:14 CET 2014 |
|
|
84 | - map key decoding was pretty much botched due to the recent cleanups. |
|
|
85 | - work around Time::Piece->epoch returning a string value, avoid encoding |
|
|
86 | this as a tag 1 string. |
|
|
87 | - enable more testcases in t/50_rfc.t, now that they work :) |
|
|
88 | |
|
|
89 | 1.2 Tue Dec 10 22:06:42 CET 2013 |
|
|
90 | - implement an incremental decoder. |
|
|
91 | |
|
|
92 | 1.12 Tue Dec 3 11:23:22 CET 2013 |
|
|
93 | - work around broken Time::Piece (in old versions of the module, %z doesn't |
|
|
94 | work as documented, gives different results on different platforms(!)). |
|
|
95 | |
|
|
96 | 1.11 Sun Dec 1 18:00:00 CET 2013 |
|
|
97 | - new setting: validate_utf8, for when you can't trust your cbor data. |
|
|
98 | - do not leak memory on decoding errors, when allow_cycles is enabled. |
|
|
99 | - add default filters for tags 0 and 1, using Time::Piece. |
|
|
100 | - more tests added. |
|
|
101 | |
|
|
102 | 1.1 Sat Nov 30 19:14:27 CET 2013 |
|
|
103 | - INCOMPATIBLE CHANGE: new decoder setting: allow_cyclic, needed to decode |
|
|
104 | cyclic data structures (to avoid memleaks in unsuspecting code). |
|
|
105 | - no longer "share" references that aren't, i.e. true/false/null/error/tagged. |
|
|
106 | - fix stringref w.r.t. indefinite-length strings. |
|
|
107 | - verify indefinite-length string chunk types. |
|
|
108 | - do not allow extremely large arrays - assume an array element |
|
|
109 | requires at least one CBOR byte, to avoid memory exhaustion attacks. |
|
|
110 | - major code overhaul. |
|
|
111 | |
|
|
112 | 1.0 Thu Nov 28 16:43:31 CET 2013 |
|
|
113 | - use the now official tag values for extensions. remove the |
|
|
114 | experimental notice. it's the real thing now, with real bugs. |
|
|
115 | - renamed allow_stringref to pack_strings. |
|
|
116 | - port to perl <= 5.16. |
|
|
117 | - slightly improve the documentation. |
|
|
118 | |
|
|
119 | 0.09 Fri Nov 22 16:54:18 CET 2013 |
|
|
120 | - bignum/bigfloat/decimal support. |
|
|
121 | - uri support. |
|
|
122 | - tag filter functions support for decoding. |
| 5 | - do not support reference-to-1/0/undef anymore, you need to use |
123 | - do not support reference-to-1/0/undef anymore, you need to use |
| 6 | the Types::Serialiser objects now. |
124 | the Types::Serialiser objects now. |

|
|
126 | - experimental stringref extension support (http://cbor.schmorp.de/stringref). |
| 8 | - implement indirection tag (http://cbor.schmorp.de/indirection). |
