Synopsis:          Moderate: rubygems security update
Advisory ID:       SLSA-2013:1441-1
Issue Date:        2013-10-17
CVE Numbers:       CVE-2012-2125
                   CVE-2012-2126
                   CVE-2013-4287
--

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)
