🌐 Web query:
node:20.19-alpine3.20 Docker image compatibility
💡 Result:
Short answer: node:20.19-alpine3.20 is an official Docker tag and works, but it uses Alpine (musl libc) so you may hit compatibility issues with glibc-linked binaries or some native (npm) modules. Recommended mitigations: install build tools (apk add build-base python3 make g++), rebuild native modules (npm rebuild / npm ci), or use gcompat/glibc compatibility — or switch to a glibc-based Node image (e.g., node:20.19-bookworm or node:20.19-slim) if you need broad binary compatibility. [1][2][3][4]

- Explanation of musl vs glibc tradeoffs for Alpine images. [2]
- Alpine docs on running glibc programs and gcompat. [3]

🌐 Web query:
Node.js 20.19 Alpine 3.20 segmentation fault
💡 Result:
Short answer — this is a known problem with some Node 20 builds on Alpine 3.20 (segfaults/instability). Causes reported include Alpine-packaged Node/OpenSSL/musl interactions and upstream Node patches; Alpine security notices and downstream projects recommend upgrading or pinning to fixed Node builds. See sources and fixes below.
What to do
- Upgrade the Alpine package to the fixed Node build (Alpine nodejs >= 20.15.1-r0) or use a newer Node 20.x that includes the fix. [1][2]
- If you can’t upgrade, run a non‑Alpine (glibc) Node image (e.g., node:20 on Debian/Bookworm) or pin to an earlier working image (reports show rolling back to 3.18/older Node removed the crash for some users). [3][4]
- If crashes look OpenSSL-related (segfault after runtime DB/crypto ops), pin OpenSSL to the prior working patch (e.g., 3.0.16) as a temporary workaround while upgrading. [5]
References
- Alpine / CVE/patch info (fixed in nodejs 20.15.1-r0). [1]
- Snyk advisory mentioning upgrade to 20.15.1-r0 for Alpine 3.20. [2]
- Community bug reports showing segfaults on Alpine 3.19/3.20 and rollbacks to older images as a workaround. [3][4]
- Report of segfaults tied to OpenSSL patch changes and suggestion to pin OpenSSL 3.0.16. [5]
If you want, tell me how you run Node (Dockerfile or image tag and exact version) and I’ll give the exact Dockerfile fix/pinning command.
🌐 Web query:
node 20.19 alpine:3.20 known issues
💡 Result:
Short summary — known issues reported for node:20.19-alpine3.20 (May 2024 → present):
-
Multiple security vulnerabilities in Alpine-packaged Node.js that affect 3.20 (including CVE‑2024‑22018 and CVE‑2024‑22020). Upgrading the Alpine nodejs package to the patched release (20.15.1-r0 or later where provided) or pulling a patched node:20-alpine image is recommended. [1][2]
-
Reported command‑injection / package-specific vulnerabilities affecting Alpine Node.js packages (CVE references for Alpine 3.19/3.20 family); monitor Alpine security advisories and update images when fixed. [3]
-
Community reports of memory‑leak/regression behavior after specific Node 20.x updates on Alpine images (users rolled back to earlier pinned images to avoid the issue). If you see unexplained memory growth, try pinning a known-good node:20.x-alpine image or using a non-Alpine base for comparison. [4]
Recommended actions:
- Pull latest node:20-alpine3.20 (or node:20-alpine with updated package) and rebuild to get patched Alpine packages. Verify the nodejs package version in the image (apk info / node -v). [1][2]
- If immediate patch unavailable, pin to a known-good image (e.g., earlier patched tag) or switch to Debian/Ubuntu‑based node images until Alpine package fixes are released. [4][1]

The Docker image node:20.19-alpine3.20 is known to have segmentation fault and instability issues with Node 20 builds on Alpine 3.20. This is caused by Alpine-packaged Node/OpenSSL/musl interactions. Additionally, this tag has known security vulnerabilities (CVE-2024-22018, CVE-2024-22020).
To actually fix segmentation faults, consider one of these approaches:
- Upgrade to patched Alpine Node build: Use
node:20.15.1-alpine3.20or ensure the Alpine nodejs package is >= 20.15.1-r0 - Switch to glibc-based image: Use
node:20.19-bookworm(ornode:20.19-slim) if broad binary compatibility is needed - Investigate root cause: If the seg fault is OpenSSL-related, pinning OpenSSL to 3.0.16 may be a temporary workaround while upgrading
Before merging, verify which version is actually required and ensure it addresses the underlying segmentation fault.

In docker/Dockerfile around line 1, the base image node:20.19-alpine3.20 is
known to cause segmentation faults and has CVEs; update the FROM to a safer
image: either pin to the patched Alpine Node build (e.g.,
node:20.15.1-alpine3.20 or any tag with nodejs >= 20.15.1-r0) or switch to a
glibc-based variant like node:20.19-bookworm or node:20.19-slim; choose the
appropriate image for your compatibility needs, update the Dockerfile FROM line
accordingly, and verify the selected tag resolves the segfault/security issues
before merging.
