Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient verification of data authenticity in Bundler, when  choosing a dependency source. The application selects a dependency source based on the highest gem version number, which means that a rogue gem found at a public source may be chosen, even if the intended choice was a private gem that is a dependency of another private gem that is explicitly depended on by the application.

Mitigation

Update the affected package ruby-bundler to version 2.2.18-1.
