Details

In versions of mruby up to and including 1.4.0, an integer overflow exists in src/vm.c::mrbvmexec() when handling OP_GETUPVAR in the presence of deep scope nesting, resulting in a use-after-free. An attacker that can cause Ruby code to be run can use this to possibly execute arbitrary code.
