Title
Potential out of bound read in _nx_secure_tls_process_clienthello()
Summary
In Eclipse Foundation NextX Duo before 6.4.4, a module of ThreadX, the _nx_secure_tls_process_clienthello() function was missing length verification of
certain SSL/TLS client hello message: the ciphersuite length and
compression method length. In case of an attacker-crafted message with
values outside of the expected range, it could cause an out-of-bound
read.
