The dl module in Ruby versions 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 fails to check the taintness of inputs. This flaw allows attackers to bypass Ruby's safe level restrictions by passing tainted data to DL.dlopen, which can result in the execution of arbitrary and potentially dangerous functions from shared libraries, even in environments intended to be sandboxed.
