The vulnerability of the SSL_check_chain function in the TLS protocol implementation of the OpenSSL library involves the possibility of reassigning the null pointer due to incorrect processing of the “signature_algorithms_cert” extension in TLS. This allows a perpetrator to cause a service failure.
