NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby2.7 package and not the ruby2.7 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Date.parse in the date gem through 3.2.0 for Ruby allows ReDoS (regular expression Denial of Service) via a long string. The fixed versions are 3.2.1, 3.1.2, 3.0.2, and 2.0.1.
