DOS attack with hash collisions (Perl rulez)by LanX (Saint) |

LanX has asked for the wisdom of the Perl Monks concerning the following question:
Hi 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
