ELSA-2023-5712: nginx:1.20 security update (MODERATE)

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js.

Various `node:fs` functions allow specifying paths as either strings or `Uint8Array` objects. In Node.js environments, the `Buffer` class extends the `Uint8Array` class. Node.js prevents path traversal through strings (see CVE-2023-30584) and `Buffer` objects (see CVE-2023-32004), but not through non-`Buffer` `Uint8Array` objects. This is distinct from CVE-2023-32004 which only referred to `Buffer` objects. However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
