wolfssl < 5.0.0 - Denial of Service via TLS Message Spoofing

Title source: llm
STIX 2.1

Description

wolfSSL through 5.0.0 allows an attacker to cause a denial of service and infinite loop in the client component by sending crafted traffic from a Machine-in-the-Middle (MITM) position. The root cause is that the client module accepts TLS messages that normally are only sent to TLS servers.
