Scientific Linux Security Update : rubygems on SL6.x (noarch) (20131017)

medium Nessus Plugin ID 70491

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)

Solution

Update the affected rubygems package.
