Last modified Jun 16, 2026

CVE-2009-0124 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.32% chance of exploitation in the next 30 days.
