NGSSoftware are going to withhold details about this flaw for three
months. Full details will be published on the 2nd of February 2005. This
three month window will allow users of WinRAR the time needed to download
the updated version before the details are released to the general public.
This reflects NGSSoftware's new approach to responsible disclosure.
This vulnerability can be detected by Typhon III - NGSSoftware's advanced

I (Peter Winter-Smith) would like to personally give thanks and
recognition to the developers of WinRAR for the speed of their delivery
of a fix for this vulnerability.
