CVE-2022-23633: Debian Linux

Medium severity, CVSS 5.9. EPSS: 2.2% chance of exploitation in the next 30 days.

Action Pack is a framework for handling and responding to web requests. Under certain circumstances response bodies will not be closed. In the event a response is *not* notified of a `close`, `ActionDispatch::Executor` will not know to reset thread local state for the next request. This can lead to data being leaked to subsequent requests.This has been fixed in Rails 7.0.2.1, 6.1.4.5, 6.0.4.5, and 5.2.6.1. Upgrading is highly recommended, but to work around this problem a middleware described in GHSA-wh98-p28r-vrc9 can be used.

Affected products

• Debian Debian Linux: version 10.0 only; version 11.0 only
• Rubyonrails Rails: from 5.0.0, before 5.2.6.2 (fixed in 5.2.6.2); from 6.0.0, before 6.0.4.6 (fixed in 6.0.4.6); from 6.1.0, before 6.1.4.6 (fixed in 6.1.4.6); from 7.0.0, before 7.0.2.2 (fixed in 7.0.2.2)
