Descriptions

Trusty contains a vulnerability in the NVIDIA OTE protocol that is present in all TAs. An incorrect message stream deserialization allows an attacker to use the malicious CA that is run by the user to cause the buffer overflow, which may lead to information disclosure and data modification.
