ProFTPD TELNET IAC Escape Sequence Remote Buffer Overflow

critical Nessus Plugin ID 70446


The remote ProFTP daemon is affected by a buffer overflow vulnerability.


The remote ProFTP daemon is susceptible to an overflow condition. The TELNET_IAC escape sequence handling fails to properly sanitize user- supplied input resulting in a stack overflow. With a specially crafted request, an unauthenticated, remote attacker could potentially execute arbitrary code.


Upgrade to version 1.3.3c or later.
