CVE-2019-8321

Name of the Vulnerable Software and Affected Versions: RubyGems versions 2.6 through 3.0.2

Description: The issue is related to insufficient escaping in the Gem::UserInteraction module of the RubyGems package management system. This allows a remote attacker to inject escape sequences, potentially compromising data integrity. The say function is called without proper escaping by Gem::UserInteraction#verbose, making escape sequence injection possible.

Recommendations: For versions 2.6 through 3.0.2, consider disabling the Gem::UserInteraction#verbose function until a patch is available to prevent escape sequence injection. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
