"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.

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."
