|Gentoo Linux Security Advisory
Title: Ruby: Denial of Service (GLSA 200906-02)
Date: June 28, 2009
A flaw in the Ruby standard library might allow remote attackers to cause a Denial of Service attack.
Ruby is an interpreted object-oriented programming language. The elaborate standard library includes the "BigDecimal" class.
Vulnerable: < 1.8.6_p369
Unaffected: >= 1.8.6_p369
Architectures: All supported architectures
Tadayoshi Funaba reported that BigDecimal in ext/bigdecimal/bigdecimal.c does not properly handle string arguments containing overly long numbers.
A remote attacker could exploit this issue to remotely cause a Denial of Service attack.
There is no known workaround at this time.
All Ruby users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.6_p369"
