Re: Bug Serious problem in NEC SOCKS server

The following bug is present at *least* in Socks5 beta-0.17.2 from NEC.  Other
versions haven't been tested, but they are most likely vulnerable as well

[ ... ]

Workarounds:

* Use mktemp to generate a unique temp file name and redirect socks to that
* The source is available, recompile *without* PID file support
* Create /tmp/socks5.pid (as root) and make sure that ordinary users can't
remove it

Or, better yet, write the pidfile in a non-sticky directory, such
as /var/run (on bsd systems).
