|
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. |
|

|
|
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). |
