Description:
Przemyslaw Frasunek has reported some vulnerabilities in tnftpd (also known as lukemftpd), which potentially can be exploited by malicious users to gain escalated privileges or compromise a vulnerable system.

Successful exploitation may allow execution of FTP commands or arbitrary code with the privileges of the tnftpd process.
