( #3333=superdoc: print w/ replies, xml ) Need Help??

Germany's biggest online-newspaper puplished today that most webservers are vulnerable because of hash-collisions in web-languages.

Since they didn't mention Perl, I did some investigation finding this publication

So Perl already fixed this in 2003 and the authors used this knowledge to attack the other languages ... xD

see also hash collision DOS

I remember that this issue was mentioned somewhere in the perldocs (IMHO regarding the unpredictable order of storing hash-values)...

Question: Can someone help me find the corresponding perldocs?

Cheers Rolf
