web security question.

[pxlpluker]

I have a friend that was using formmail.pl until last weekend when it 
was hacked by spammers with a buffer overflow attack on one of the form 
fields. I don't know enough about perl to know how/where  the overflow 
happened. I do have a raw copy of the data the spammer was using, he was 
putting about 40k into a form field to break the script. I am guessing 
it broke the script on the regex checking for valid emails or before.
My question is, is python open to such attacks and how to prevent it.
I am working on a web program that will have a email address and will 
send an email/s.
would a buffer overflow attack work against python cgi ?
