Ruby 1.9.1-p376 is released

Ruby 1.9.1-p376 just has been released. This is a patch level release of Ruby 1.9.1 and includes the fix of CVE-2009-4124.


The previous release, Ruby 1.9.1-p243 has a security vulnerability that allows heap overflow. This vulnerability was found by Emmanouel Kellinis, KPMG London.

I recommend all Ruby 1.9.1 users to upgrade to p376. But the vulnerability does not affect Ruby 1.8 series.
