two things. number one, i stated that you will most likely have to brute
force the offset (make a bash/perl script to try running the exploit with
different offsets) because i wrote it for my _slackware_ box, and number
two, as stated before, ddate is NOT suid, therefore you will not recieve
elevated privaledges (your id wont change).

I found a buffer overflow in /usr/bin/ddate (version unknown) "converts
Gregorian dates to Discordian dates.."
I tested it on my Linux Box (RedHat 6.2)
Look at this:

#ddate +AAAA...x 408
