The Fiddle::Handle implementation in ext/fiddle/handle.c in Ruby before
2.0.0-p648, 2.1 before 2.1.8, and 2.2 before 2.2.4, as distributed in Apple
OS X before 10.11.4 and other products, mishandles tainting, which allows
context-dependent attackers to execute arbitrary code or cause a denial of
service (application crash) via a crafted string, related to the DL module
and the libffi library. NOTE: this vulnerability exists because of a
CVE-2009-5147 regression.
