The remote FreeBSD host is missing a security-related update.
A Gentoo Linux Security Advisory reports :
Florian Schilhabel of the Gentoo Linux Security Audit project found a
format string vulnerability in Proxytunnel. When the program is
started in daemon mode (-a [port]), it improperly logs invalid proxy
answers to syslog.
A malicious remote server could send specially crafted invalid answers
to exploit the format string vulnerability, potentially allowing the
execution of arbitrary code on the tunnelling host with the rights of
the Proxytunnel process.
