Multiple stack-based buffer overflows in the pr_netio_telnet_gets
function in netio.c in ProFTPD before 1.3.3c allow remote attackers to
execute arbitrary code via vectors involving a TELNET IAC escape
character to a (1) FTP or (2) FTPS server.

Note: the impact of this is somewhat lessened as proftpd runs as the 'nobody' user.  According to upstream, this vulnerability has been present since 1.3.2rc3.
