Multiple vulnerabilities in Ruby

[Mark Painter]

Some vulnerabilities have been reported in Ruby, which can be exploited by malicious people to bypass certain security restrictions, cause a DoS (Denial of Service), and conduct spoofing attacks.

http://www.ruby-lang.org/en/news/2008/08/08/multiple-vulnerabilities-in-ruby/

Vulnerable versions

1.8 series

        * 1.8.5 and all prior versions
        * 1.8.6-p286 and all prior versions
        * 1.8.7-p71 and all prior versions

1.9 series

        * r18423 and all prior revisions

I hate to be a nag, but this package is in main, and it's been a month, and well, the SABDFL seems to think Ubuntu has a good track record with security fixes...

"Well we have a better security track record than Red Hat, we do that by focusing very hard on security, making sure the updates are available as fast as possible on Ubuntu, independent studies have generally ranked Ubuntu number one."

Any chance it can get fixed?

Thanks for the ping. We are working on it, but other updates have taken priority over Ruby. The open Ruby vulnerabilities are mostly denial-of-service or untrusted local script issues, which have traditionally been low priority.
