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
-------------------------------------------------------------------
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.
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"
