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"
