Ruby security vulnerabilities

Here is the news from the Rails Log:

Drew Yao at Apple uncovered a handful of nasty security vulnerabilities affecting all current versions of Ruby. The details are still under wraps because an attacker can DoS you or possibly execute arbitrary code—holy crap! Better upgrade sooner than later.

According to the official Ruby security advisory, the vulnerable Rubies are:

• 1.8.4 and earlier
• 1.8.5-p230 and earlier
• 1.8.6-p229 and earlier
• 1.8.7-p21 and earlier

Those of us running Ruby 1.8.4 or earlier must upgrade to 1.8.5 or later for a fix. Those on 1.8.5-7 can grab the latest patchlevel release for a fix.

(Please note: Ruby 1.8.7 breaks backward compatibility and is only compatible with Rails 2.1 and later, so don’t go overboard!)
