Overview
Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) via the bson_new_from_buffer function. An attacker can cause a crash by supplying crafted BSON data with a zero-length prefix, leading to a heap out-of-bounds read when the function fails to validate the minimum document size.
