libraries.

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)

Red Hat would like to thank Rubygems upstream for reporting CVE-2013-4287.
Upstream acknowledges Damir Sharipov as the original reporter.

All rubygems users are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
