LanX has asked for the wisdom of the Perl Monks concerning the following question:
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
http://www.nruns.com/_downloads/advisory28122011.pdf
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
