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.
