SUSE SLES15 Security Update : nodejs20 (SUSE-SU-2026:1363-1)

high Nessus Plugin ID 306701

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:1363-1 advisory.

Update to version 20.20.2.

- CVE-2026-21717: trivially predictable hash collisions due to flaw in V8's string hashing mechanism allows for performance degradation via a crafted request (bsc#1260494).
- CVE-2026-21716: incomplete fix for CVE-2024-36137 allows promise-based FileHandle methods to be used to modify file permissions and ownership on already-open file descriptors (bsc#1260462).
- CVE-2026-21715: flaw in the Permission Model filesystem enforcement allows for file existence disclosure and filesystem path enumeration via `fs.realpathSync.native()` (bsc#1260482).
- CVE-2026-21714: memory leak in Node.js HTTP/2 server allows for resource exhaustion via `WINDOW_UPDATE` frames sent on stream 0 (bsc#1260480).
- CVE-2026-21713: timing side-channel due to flaw in Node.js HMAC verification allows for discovery of HMAC values and potential MAC forgery (bsc#1260463).
- CVE-2026-21710: uncaught `TypeError` when handling HTTP requests allows for a process crash via requests with a header named `__proto__` when the application accesses `req.headersDistinct` (bsc#1260455).
- CVE-2026-21637: flaw in TLS error handling allows for resource exhaustion and crash when `pskCallback` or `ALPNCallback` are in use (bsc#1256576).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected nodejs20, nodejs20-devel, nodejs20-docs and / or npm20 packages.
