RHSA-2015:2180 - Security Advisory

Topic

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.

Description

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.

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. (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.
