Denial of Service Vulnerability in ActiveRecord's PostgreSQL adapter
There is a potential denial of service vulnerability present in ActiveRecord's PostgreSQL adapter.

This has been assigned the CVE identifier CVE-2022-44566.

Versions Affected: All. Not affected: None.

## Fixed Versions

- 2.3.18.47 (Rails LTS, which is a paid service and not part of the rubygem)
- 3.2.22.34 (Rails LTS, which is a paid service and not part of the rubygem)
- 4.2.11.27 (Rails LTS, which is a paid service and not part of the rubygem)
- 5.2.8.15 (Rails LTS, which is a paid service and not part of the rubygem)
- 6.1.7.1
- 7.0.4.1

## Impact

In ActiveRecord < 7.0.4.1 and < 6.1.7.1, when a value outside the range for a 64bit signed integer is provided to the PostgreSQL connection adapter, it will treat the target column type as numeric. Comparing integer values against numeric values can result in a slow sequential scan resulting in potential Denial of Service.

## Releases

The fixed releases are available at the normal locations.

## Workarounds

Ensure that user supplied input which is provided to ActiveRecord clauses do not contain integers wider than a signed 64bit representation or floats. 

## Patches

To aid users who aren't able to upgrade immediately we have provided patches for the supported release series in accordance with our maintenance policy 1 regarding security issues. They are in git-am format and consist of a single changeset.

 6-1-Added-integer-width-check-to-PostgreSQL-Quoting.patch - Patch for 6.1 series
 7-0-Added-integer-width-check-to-PostgreSQL-Quoting.patch - Patch for 7.0 series

Possible Content Security Policy bypass in Action Dispatch
There is a possible Cross Site Scripting (XSS) vulnerability  in the `content_security_policy` helper in Action Pack.

Impact
------
Applications which set Content-Security-Policy (CSP) headers dynamically from untrusted user input may be vulnerable to carefully crafted inputs being able to inject new directives into the CSP. This could lead to a bypass of the CSP and its protection against XSS and other attacks.

Releases
--------
The fixed releases are available at the normal locations.

Workarounds
-----------
Applications can avoid setting CSP headers dynamically from untrusted input, or can validate/sanitize that input.
