"A flaw was found in the way the Ruby POP module processed certain APOP
authentication requests. By sending certain responses when the Ruby
APOP module attempted to authenticate using APOP against a POP server,
a remote attacker could, potentially, acquire certain portions of a
user's authentication credentials. (CVE-2007-1558)

It was discovered that Ruby did not properly check the return value
when verifying X.509 certificates. This could, potentially, allow a
remote attacker to present an invalid X.509 certificate, and have Ruby
treat it as valid. (CVE-2009-0642)

A flaw was found in the way Ruby converted BigDecimal objects to Float
numbers. If an attacker were able to provide certain input for the
BigDecimal object converter, they could crash an application using
this class. (CVE-2009-1904)"
