Summary

[none]

Details

A flaw was found in the Netty STOMP codec. A remote attacker could send a specially crafted STOMP frame with a content-length header exceeding the maximum integer value. This integer truncation vulnerability could lead to an infinite decode loop, causing a Denial of Service (DoS) by exhausting memory and CPU resources.
