Red Hat Security Advisory 2015-2180-07 - 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. 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.
