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)

RubyGems before 1.8.23 can redirect HTTPS connections to HTTP, which makes it easier for remote attackers to observe or modify a gem during installation via a man-in-the-middle attack.

From Red Hat Security Advisory 2013:1441 :

An updated rubygems package that fixes three security issues is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

It was discovered that Ruby incorrectly allowed untainted strings to be modified in protective safe levels. An attacker could use this flaw to bypass intended access restrictions. (CVE-2011-1005)

John Firebaugh discovered that the RubyGems remote gem fetcher did not properly verify SSL certificates. A remote attacker could exploit this to perform a man in the middle attack to alter gem files being downloaded for installation. (CVE-2012-2126)

Updated Grid component packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.4 for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers.

MRG Grid provides high-throughput computing and enables enterprises to achieve higher peak computing capacity as well as improved infrastructure utilization by leveraging their existing technology to build high performance grids. MRG Grid provides a job-queueing mechanism, scheduling policy, and a priority scheme, as well as resource monitoring and resource management. Users submit their jobs to MRG Grid, where they are placed into a queue. MRG Grid then chooses when and where to run the jobs based upon a policy, carefully monitors their progress, and ultimately informs the user upon completion.

(CVE-2013-4287)

A flaw was found in the way cumin enforced user roles, allowing an unprivileged cumin user to access a range of resources without having the appropriate role. A remote, authenticated attacker could use this flaw to access privileged information, and perform a variety of privileged operations. (CVE-2013-4404)

It was found that multiple forms in the cumin web interface did not protect against Cross-Site Request Forgery (CSRF) attacks. If a remote attacker could trick a user, who is logged into the cumin web interface, into visiting a specially crafted URL, the attacker could perform actions in the context of the logged in user. (CVE-2013-4405)

It was found that cumin did not properly escape input from the 'Max allowance' field in the 'Set limit' form of the cumin web interface. A remote attacker could use this flaw to perform cross-site scripting (XSS) attacks against victims by tricking them into visiting a specially crafted URL. (CVE-2013-4414)

A flaw was found in the way cumin parsed POST request data. A remote attacker could potentially use this flaw to perform SQL injection attacks on cumin's database. (CVE-2013-4461)

Red Hat would like to thank Rubygems upstream for reporting CVE-2013-4287. Upstream acknowledges Damir Sharipov as the original reporter of CVE-2013-4287. The CVE-2013-4404, CVE-2013-4405, CVE-2013-4414, and CVE-2013-4461 issues were discovered by Tomas Novacik of the Red Hat MRG Quality Engineering team.

All users of the Grid capabilities of Red Hat Enterprise MRG are advised to upgrade to these updated packages, which correct these issues.

New version 1.8.23 is released.

The remote Solaris system is missing necessary patches to address security updates :

  - RubyGems before 1.8.23 can redirect HTTPS connections to     HTTP, which makes it easier for remote attackers to     observe or modify a gem during installation via a     man-in-the-middle attack. (CVE-2012-2125)

  - RubyGems before 1.8.23 does not verify an SSL     certificate, which allows remote attackers to modify a     gem during installation via a man-in-the-middle attack.
    (CVE-2012-2126)

With this new rubygems, HTTPS connection no longer redirects to HTTP.
Also now rubygems verify SSL connection.
