description

NetX Duo installations using NetX Secure TLS 1.3 certificate-message processing are affected. A remote peer can cause the parser to read beyond its packet buffer before authentication by submitting a malformed Certificate message.

mitigation

Upgrade NetX Duo to version 6.5.2.202603 or later. Until upgraded, reduce exposure by limiting untrusted access to TLS 1.3 endpoints using the affected stack.

fixed in 6.5.2.202603
