This bug just got reported on the Rails security list as well, which is out in the open. It also points to this news item:

http://www.ruby-lang.org/en/news/2009/06/09/dos-vulnerability-in-bigdecimal/

I've added both new versions to CVS, but I have not tested them very well yet.

Alex: I did confirm that 1.8.7_173 fixes my threading issues.

After all security-supported architectures have stabled the package, yes.

CVE-2009-1904 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1904):
  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.
