"The Ruby programming language, which has become popular as the basis for web 2.0 sites such as Twitter, contains serious security flaws that could allow attackers to take over an organization's web server, according to the Ruby development team.
The "disturbing" flaws, which were disclosed on Friday, could affect nearly any typical Ruby-based web application, according to Thomas Ptacek, founder of security firm Matasano.
The five bugs affect Ruby version 1.8 up to 1.8.7-p21 and version 1.9 up to 1.9.0-1, according to the Ruby development team.
Users can remedy the problem by upgrading to a patched version of Ruby, developers said, with patches available on the Ruby language site. "
