Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update
Severity
Important
Notes
Topic: An update for Red Hat Hardened Images RPMs is now available.
Details: This update includes the following RPMs:
ruff:
* python3-ruff-0.15.11-1.hum1 (noarch)
* ruff-0.15.11-1.hum1 (aarch64, x86_64)
* ruff-0.15.11-1.hum1.src (src)

A flaw was found in DOMPurify, a software library used to clean potentially malicious code from web content, preventing Cross-Site Scripting (XSS) attacks. A remote attacker could exploit a vulnerability related to 'prototype pollution' to bypass DOMPurify's security checks. This allows the attacker to inject harmful code, such as event handlers, into web pages. If successfully exploited, this could lead to the execution of arbitrary code in a user's web browser.

Threats
Impact
Moderate
A flaw was found in DOMPurify. A remote attacker could exploit this cross-site scripting (XSS) vulnerability when DOMPurify is configured to return a Document Object Model (DOM) or DOM fragment. The SAFE_FOR_TEMPLATES feature, intended to strip template expressions like {{...}}, fails in these modes, allowing malicious content to bypass sanitization. This can lead to arbitrary code execution or information disclosure in applications utilizing template-evaluating frameworks such as Vue 2.

Threats
Impact
Moderate
A flaw was found in Nix. Unbounded recursion in the NAR (Nix Archive) parser could lead to a stack-to-heap overflow when the parser is run on a coroutine stack. The stack is allocated without a guard page, which means that a stack overflow could overwrite memory on the heap and could allow arbitrary code execution as the Nix daemon (run as root in multi-user installations) if ASLR hardening is bypassed. This can be exploited by all users able to connect to the daemon (e.g., in Nix, this is configurable via the allowed-users setting, defaulting to all users).
