Scientific Linux Security Update : rubygems on SL6.x (noarch)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

It was found that RubyGems did not verify SSL connections. This could
lead to man-in-the-middle attacks. (CVE-2012-2126)

It was found that, when using RubyGems, the connection could be
redirected from HTTPS to HTTP. This could lead to a user believing
they are installing a gem via HTTPS, when the connection may have been
silently downgraded to HTTP. (CVE-2012-2125)

It was discovered that the rubygems API validated version strings
using an unsafe regular expression. An application making use of this
API to process a version string from an untrusted source could be
vulnerable to a denial of service attack through CPU exhaustion.
(CVE-2013-4287)
