The tqsl_verifyDataBlock function in openssl_cert.cpp in American Radio
Relay League (ARRL) tqsllib 2.0 does not properly check the return value
from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to
bypass validation of the certificate chain via a malformed SSL/TLS
signature, a similar vulnerability to CVE-2008-5077.
