* Fix integer overflows.Tobias Stoeckmann2020-05-061-3/+16
| | | | | | | | | | | | The data structures linkhash and printbuf are limited to 2 GB in size due to a signed integer being used to track their current size. If too much data is added, then size variable can overflow, which is an undefined behaviour in C programming language. Assuming that a signed int overflow just leads to a negative value, like it happens on many sytems (Linux i686/amd64 with gcc), then printbuf is vulnerable to an out of boundary write on 64 bit systems.

* initialize null terminator of new printbufPierce Lopez2016-07-161-0/+1
| | | | | | | | It's possible (e.g. by using json_object_from_file() on an empty file) to get json-c to try to use a printbuf that has never had anything written to it. Before this change, it could access a string that should be length zero, but was never initialized, and could theoretically have an unexpected string.

* Some updates to make the code compatible with VC 9 (2008)John Arbash Meinel2012-02-011-1/+1
| | | | | VC 9 doesn't support late variable declarations, and doesn't have inttypes so we need some direct definitions of a couple of more types.
* Simplify things by storing integer values only as int64_t's internally, andehaszla2010-12-071-1/+1
| | | | | | | | | | omit the range check during parsing since we already have the checks when accessing the value. There is no longer a json_type_int64, only json_type_int. Fix some problems with parsing 0 and -0 values, and add a couple of tests.
