Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the bsonObjToArray() function. An attacker can cause the server to access freed memory, potentially leading to disclosure of sensitive information from process memory or a denial of service by crashing the server, by executing server-side JavaScript after authentication with read privileges (such as via $where or $function).
