Scientific Linux Security Update : ruby on SL4.x, SL5.x i386/x86_64

Medium Nessus Plugin ID 60613


The remote Scientific Linux host is missing one or more security updates.


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)


Update the affected packages.
