http://security.gentoo.org/

Severity:	normal
Title:	Ruby: Denial of Service issue
Date:	11/16/2004
Bugs:	#69985
ID:	200411-23

Synopsis

The CGI module in Ruby can be sent into an infinite loop, resulting in a Denial of Service condition.

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	Architecture(s)
dev-lang/ruby	< 1.8.2_pre3	>= 1.6.8-r12	All supported architectures

Description

Ruby's developers found and fixed an issue in the CGI module that can be triggered remotely and cause an infinite loop.

Impact

A remote attacker could trigger the vulnerability through an exposed Ruby web application and cause the server to use unnecessary CPU resources, potentially resulting in a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Ruby 1.6.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.6.8-r12"

All Ruby 1.8.x users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.2_pre3"
