Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the print_string_ptr function when processing specially crafted JSON strings containing a large number of control characters on 32-bit platforms. An attacker can cause a heap buffer overflow by supplying such a string to an application using the affected library, potentially resulting in remote code execution, information disclosure, or denial of service.
