29th percentile - higher than 29% of all known CVEs

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.

Risk Assessment

An attacker could exploit this to access sensitive information or cause a system crash.

Recommendation

Update Eclipse Foundation NextX Duo to version 6.4.4 or later.
