Background ========= Ruby is an interpreted scripting language for quick and easy object-oriented programming. Ruby's CGI module can be used to build web applications. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/ruby < 1.8.2_pre3 *> = 1.6.8-r12 > = 1.8.2_pre3 Description ========== Ruby's developers found and fixed an issue in the CGI module that can be triggered remotely and cause an infinite loop.
