Red Hat Security Advisory 2023-5850-01 - Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2023-5849-01 - Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Issues addressed include a denial of service vulnerability.

### Impact A `__proto__` pollution vulnerability exists in synchrony versions before v2.4.4. Successful exploitation could lead to arbitrary code execution. ### Summary A `__proto__` pollution vulnerability exists in the [LiteralMap] transformer allowing crafted input to modify properties in the Object prototype. When executing in Node.js, due to use of the `prettier` module, defining a `parser` property on `__proto__` with a path to a JS module on disk [causes a `require` of the value][prettier/src/main/parser.js] which can lead to arbitrary code execution. ### Patch A fix has been released in `[email protected]`. ### Mitigation - Upgrade synchrony to v2.4.4 - Launch node with the [--disable-proto=delete][disable-proto] or [--disable-proto=throw][disable-proto] flag ### Proof of Concept Craft a malicious input file named `poc.js` as follows: ```js // Malicious code to be run after this file is imported. Logs the result of shell command "dir" to the console. console.log(req...

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 ([report 2038134](https://hackerone.com/reports/2038134)), which only referred to `Buffer` objects. However, the vulnerability follows the same pattern using `Uint8Array` instead of `Buffer`. Impacts: This vulnerability affects all users using the experimental permission model in Node.js 20. 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.

Vulnerability in the Sun ZFS Storage Appliance product of Oracle Systems (component: Core). The supported version that is affected is 8.8.60. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Sun ZFS Storage Appliance. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Sun ZFS Storage Appliance. CVSS 3.1 Base Score 5.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).
