Title of the patch: Security update for uftpd
Description of the patch: This update for uftpd fixes the following issues: uftpd was updated to version 2.12. Changes: * Use common log message format and log level when user enters an invalid path. This unfortunately affects changes introduced in v2.11 to increase logging at default log level. Security fixes: - CVE-2020-14149: When entering an invalid directory with the FTP command CWD, a NULL ptr was deref. in a DBG() message even though the log level is set to a value lower than LOG_DEBUG.
