Integer overflow in the (1) rb_ary_splice function in Ruby 1.8.4 and earlier, 1.8.5 before 1.8.5-p231, 1.8.6 before 1.8.6-p230, 1.8.7 before 1.8.7-p22, and 1.9.0 before 1.9.0-2; and (2) the rb_ary_replace function in 1.6.x allows context-dependent attackers to trigger memory corruption, aka the "beg + rlen" issue.
