A format string vulnerability in telnetd-ssl 0.17 and earlier allows remote attackers to execute arbitrary code via crafted SSL error messages.

Vulnerability

telnetd-ssl, part of the Debian Netkit package, contains a format string vulnerability in versions 0.17 and earlier. The flaw occurs when the server processes specially crafted SSL error messages [1].

Exploitation
