Overview

Affected versions of this package are vulnerable to Improper Validation of Certificate Expiration. If the user added a security exception for an invalid TLS certificate, opened an ongoing TLS connection with a server that used that certificate, and then deleted the exception, Firefox would have kept the connection alive, making it seem like the certificate was still trusted.
