Mandriva Linux Security Advisory 2013-286 - Heap-based buffer overflow in Ruby 1.8, 1.9 before 1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0 preview2, and trunk before revision 43780 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via a string that is converted to a floating point value, as demonstrated using JSON.parse. The updated packages have been patched to correct these issues.
