The vulnerability of the implementations of the functions netclear() and nextitem() in the demon telnetd of the netkit-telnet server allows a intruder to execute arbitrary code.

The vulnerability of the implementations of the functions netclear and nextitem in the telnetd daemon of the netkit-telnet server is related to the copying of buffers without checking the size of the input data. Exploiting this vulnerability could allow an attacker to execute arbitrary code by...
