The vulnerability of the MessagePack NodeJS/JavaScript msgpackr implementation allows a hacker to cause a service failure.

The vulnerability of the MessagePack NodeJS/JavaScript msgpackr implementation lies in the ability for users to execute suspended threads, creating messages that lock the decoder. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

Denial Of Service

msgpackr is vulnerable to Denial Of Service DoS. The vulnerability is due to faulty validation for user supplied MessagePack messages. An attacker can trigger an infinite loop by specially crafted messages, resulting in Denial of Service...
