[ruby-core:28011] [Bug #2707] Denial of Service with Date>> operator for large numbers of n

From: Zev Blut <redmine@...>
Date: 2010-02-02 16:09:28 UTC
List: ruby-core #28011
Bug #2707: Denial of Service with Date>> operator for large numbers of n
http://redmine.ruby-lang.org/issues/show/2707

Author: Zev Blut
Status: Open, Priority: Low
Category: lib, Target version: Ruby 1.8.6
ruby -v: ruby 1.8.6 (2009-06-08 patchlevel 369) [i686-linux]

I am not sure this is a realistic issue, but my colleagues and I discovered a fun way to consume cpu for a long time.

For any n >= 1e16

ruby -v 
ruby 1.8.6 (2009-06-08 patchlevel 369) [i686-linux]

> require 'date'
> n = 1e16
> Date.today >> (n* 12)

On 1.9 this might not be a problem:
ruby -v
ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]

ruby-1.9.1-p243 > RUBY_VERSION
 => "1.9.1" 
ruby-1.9.1-p243 > require 'date'

ruby-1.9.1-p243 > Date.today >> (n* 12)
