Description
This security bulletin contains information about 1 security vulnerability.
1) Insufficient verification of data authenticity (CVE-ID: CVE-2020-36327)
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.
Remediation
Install update from vendor's website.
