Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the JSON parsing process. An attacker can cause the application to terminate unexpectedly by supplying a specially crafted large JSON input, leading to memory corruption and potential denial of service. This is only exploitable if the application is built for a 32-bit environment.
