NVD Description

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

Rack is a modular Ruby web server interface. Carefully crafted headers can cause header parsing in Rack to take longer than expected resulting in a possible denial of service issue. Accept and Forwarded headers are impacted. Ruby 3.2 has mitigations for this problem, so Rack applications using Ruby 3.2 or newer are unaffected. This vulnerability is fixed in 2.0.9.4, 2.1.4.4, 2.2.8.1, and 3.0.9.1.
