RHSA-2026:7675 - Security Advisory

标题

An update for nodejs24 is now available for Red Hat Enterprise Linux 10.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

描述

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Security Fix(es):

• nodejs: Nodejs denial of service (CVE-2026-21637)
• brace-expansion: brace-expansion: Denial of Service via unbounded brace range expansion (CVE-2026-25547)
• minimatch: minimatch: Denial of Service via specially crafted glob patterns (CVE-2026-26996)
• undici: Undici: Denial of Service due to uncontrolled resource consumption (CVE-2026-2581)
• undici: Undici: HTTP header injection and request smuggling vulnerability (CVE-2026-1527)
• undici: undici: Denial of Service via unbounded memory consumption during WebSocket permessage-deflate decompression (CVE-2026-1526)
• undici: Undici: Denial of Service via invalid WebSocket permessage-deflate extension parameter (CVE-2026-2229)
• undici: Undici: HTTP Request Smuggling and Denial of Service due to duplicate Content-Length headers (CVE-2026-1525)
• undici: undici: Denial of Service via crafted WebSocket frame with large length (CVE-2026-1528)
• nghttp2: nghttp2: Denial of Service via malformed HTTP/2 frames after session termination (CVE-2026-27135)
• Node.js: Node.js: Denial of Service via malformed Internationalized Domain Name processing (CVE-2026-21712)
• Node.js: Node.js: Denial of Service due to crafted HTTP `__proto__` header (CVE-2026-21710)
• Node.js: Node.js: Information disclosure due to `fs.realpathSync.native()` bypassing filesystem read restrictions (CVE-2026-21715)
• nodejs: Node.js: Permission bypass allows unauthorized modification of file permissions and ownership via incomplete security fix. (CVE-2026-21716)
• Node.js: Node.js: Unauthorized inter-process communication due to missing Unix Domain Socket permission checks (CVE-2026-21711)
• Node.js: Node.js: Information disclosure via timing oracle in HMAC verification (CVE-2026-21713)
• Node.js: Node.js: Memory leak and Denial of Service via crafted HTTP/2 WINDOW_UPDATE frames (CVE-2026-21714)
• nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions (CVE-2026-21717)
