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 < 1.8.4-r1 >= 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 ">=dev-lang/ruby-1.8.4-r1"
