Insight

Insight

Ruby is an interpreted scripting language for quick and easy object-oriented programming. The Ruby DNS resolver library, resolv.rb, used predictable transaction IDs and a fixed source port when sending DNS requests. A remote attacker could use this flaw to spoof a malicious reply to a DNS query. (CVE-2008-3905) A number of flaws were found in the safe-level restrictions in Ruby. It was possible for an attacker to create a carefully crafted malicious script that can allow the bypass of certain safe-level restrictions. (CVE-2008-3655) A denial of service flaw was found in Ruby's regular expression engine. If a Ruby script tried to process a large amount of data via a regular expression, it could cause Ruby to enter an infinite-loop and crash. (CVE-2008-3443) Users of ruby should upgrade to these updated packages, which contain backported patches to resolve these issues.
