How to fix?

Upgrade Debian:unstable jruby to version 9.3.9.0+ds-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jruby package and not the jruby package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."
