The option processing function (telrcv) in the daemon produces responses with a fixed size buffer, but does not perform bounds checking. Attackers can send a combination of TELNET protocol options to the daemon to overflow the buffer and execute arbitrary commands.") ) ) :color (red) :severity (5) :category (TELNET) :keywords ("telnet dangerous command bin") )
