Synopsis
========
Ruby is vulnerable to a security bypass of the safe level mechanism.
Background
==========
Ruby is an interpreted scripting language for quick and easy
object-oriented programming. Ruby supports the safe execution of
untrusted code using a safe level and taint flag mechanism.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/ruby < 1.8.3 >= 1.8.3
Description
===========
Dr. Yutaka Oiwa discovered that Ruby fails to properly enforce safe
level protections.
Impact
======
An attacker could exploit this vulnerability to execute arbitrary code
beyond the restrictions specified in each safe level.
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-1.8.3"
