http://security.gentoo.org/

Severity:	normal
Title:	Ruby: Security bypass vulnerability
Date:	10/06/2005
Bugs:	#106996
ID:	200510-05

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	Architecture(s)
dev-lang/ruby	< 1.8.3	>= 1.8.3	All supported architectures

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"
