Synopsis
========

Ruby WEBrick and XMLRPC servers are vulnerable to Denial of Service.

Background
==========

Ruby is an interpreted scripting language for quick and easy
object-oriented programming. It comes bundled with HTTP ("WEBrick") and
XMLRPC server objects.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/ruby lt; 1.8.4-r1 gt;= 1.8.4-r1

Description
===========

Ruby uses blocking sockets for WEBrick and XMLRPC servers.

Impact
======

An attacker could send large amounts of data to an affected server to
block the socket and thus deny other connections to the server.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ruby users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-lang/ruby-1.8.4-r1"
