Bundler before 1.7, when multiple top-level source lines are used, allows remote attackers to install arbitrary gems by creating a gem with the same name as another gem in a different source.

The remote host is affected by the vulnerability described in GLSA-201609-02 (Bundler: Insecure installation)

    Bundler, allows the installation of gems from different sources with the       same names, when multiple top-level gem sources are used.
  Impact :

    Remote attackers could inject arbitrary code via the gem install       process.
  Workaround :

    There is no known workaround at this time.

A flaw was found in the way Bundler handled gems available from multiple sources. An attacker with access to one of the sources could create a malicious gem with the same name, which they could then use to trick a user into installing, potentially resulting in execution of code from the attacker-supplied malicious gem. (CVE-2013-0334)

Bundler has been upgraded to upstream version 1.7.8 and Thor has been upgraded to upstream version 1.19.1, both of which provide a number of bug fixes and enhancements over the previous versions.

Updated rubygem-bundler and rubygem-thor packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Bundler manages an application's dependencies through its entire life, across many machines, systematically and repeatably. Thor is a toolkit for building powerful command-line interfaces.

Bundler has been upgraded to upstream version 1.7.8 and Thor has been upgraded to upstream version 1.19.1, both of which provide a number of bug fixes and enhancements over the previous versions. (BZ#1194243, BZ#1209921)

All rubygem-bundler and rubygem-thor users are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2015-2180 advisory.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

rubygem-bunder was updated to fix security vulnerabilities and non-security issues

The following security issues were fixed :

  - Hide credentials while warning about gems with ambiguous     sources

  - Warn when more than one top-level source is present

  - Bundler may install gems from a different source than     expected (CVE-2013-0334) (bnc#898205)

In addition, rubygem-bundler was udpated to 1.8.4 to fix non-security issues.

This update fixes CVE-2013-0334: 'bundle install' may install a gem from a source other than expected

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
