Description

The dl module in Ruby 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 does not check "taintness" of inputs, which allows context-dependent attackers to bypass safe levels and execute dangerous functions by accessing a library using DL.dlopen.

Affected configurations

• ruby-lang ruby (<= 1.8.5) • ruby-lang ruby 1.6.8 • ruby-lang ruby 1.8.0 • ruby-lang ruby 1.8.1 • ruby-lang ruby 1.8.2 • ruby-lang ruby 1.8.3 • ruby-lang ruby 1.8.4 • ruby-lang ruby 1.8.5 • ruby-lang ruby 1.8.6 • ruby-lang ruby 1.8.7 • ruby-lang ruby 1.9.0
