A misconfigured wildcard TLS certificate causes a stack read overflow. This issue does not affect any wildcard certificate issued to the RFC9525 standard - the fix only accepts certificates that comply to this standard. This issue affects Apache Qpid Proton C: through 0.40.0. Users are recommended to upgrade to version 0.41.1, which fixes the issue.
