Description

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.
