Description Andrej Nemec 2016-10-05 12:19:13 UTC

A vulnerability was found in Bundler. Bundler allows the user to specify sources from which Ruby gems are installed. If a secondary source is specified, even if scoped to a specific gem, that source is silently applied to all declared gems. This allows an attacker to introduce arbitrary code into an application via gem name collision on the secondary source, which will unexpectedly (and without warning) take priority over the primary source.
