Potential realloc function

[MicroMilo]

I noticed a lot of realloc functions being used in projects, but I think there is one that may have a potential CWE401 memory leak.

location: src\jansson\src\strbuffer.c#strbuffer_append_bytes:74

strbuff->value = realloc(strbuff->value, strbuff->size);

Once strbuff->size is too big, the operation will fail, and then the original strbuff->value will leak. Then I watch on the call chain about the function strbuffer_append_bytes.

• ws_process_read_data, websocket.c
• ws_execute, websocket.c
• json_reply, formats/json.c
• json_string_output, formats/json.c
• json_dumps, jansson/src/dump.c
• dump_to_strbuffer, jansson/src/dump.c

due to the function ws_process_read_data, I think it is possible to cause realloc function failed.
