Ruby is an interpreted object-oriented programming language. The
elaborate standard library includes the "BigDecimal" class.
Tadayoshi Funaba reported that BigDecimal in
ext/bigdecimal/bigdecimal.c does not properly handle string arguments
containing overly long numbers.
<impact type="normal">
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 &quot;&gt;=dev-lang/ruby-1.8.6_p369&quot;</code>
