Update to new upstream release fixing multiple security issues detailed in the upstream advisories:
http://www.ruby-lang.org/en/news/2008/08/08/multiple- vulnerabilities-in-ruby/ - CVE-2008-3655 - multiple insufficient safe mode restrictions - CVE-2008-3656 - WEBrick DoS vulnerability (CPU consumption) - CVE-2008-3657 - missing βtaintnessβ checks in dl module
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
