Insight
The BigDecimal library in Ruby 1.8.6 before p369 and 1.8.7 before p173 allows context-dependent attackers to cause a denial of service (application crash) via a string argument that represents a large number, as demonstrated by an attempted conversion to the Float data type. This update corrects the problem. Affected: 2008.1, 2009.0, 2009.1, Corporate 3.0, Corporate 4.0
