wolfSSL.wolfssl is vulnerable to Integer underflow

Low Risk
This Affects:
wolfSSL.wolfsslTL;DR
The TLS packet sniffer path decodes AEAD records with a length underflow when a record is shorter than the explicit IV plus authentication tag, wrapping a 16-bit length to a large value passed into AEAD decryption and corrupting heap memory. The feature requires --enable-sniffer and AEAD. The fix validates record lengths before decryption.
Who does this affect?
