Fwd: solution to wu-ftpd + tar program execution

["smith jerome" <securebox () hotmail com>]

This has been known for a long time:
http://www.security-express.com/archives/bugtraq/1999-q4/0405.html

There is an easy solution to this which don't cut functionality:
in ftpconversions place " -- " before "%s" in every line which has tar
(probably on all lines is a good idea).
" -- " terminates the arguments passed to tar, so programs can't be
injected.

linux distributions were notified about the solution, debian released an
advisory at:
