Fix critical CVEs in image-builder-bob: bump buildkit base to v0.20.1-gitpod.7#21414
Conversation
…-gitpod.7 Upgrades the pinned buildkit base image to pull in: - CVE-2026-31789 (Critical) — OpenSSL libssl3/libcrypto3 in Alpine - CVE-2025-68121 (Critical) — Go crypto/tls session resumption Both criticals were tripping the daily scheduled vulnerability gate in `Build / Build Gitpod / Check for Critical Vulnerabilities` against `components/image-builder-bob:docker`. The new tag rebases on Alpine 3.23 and Go 1.26.2 in upstream BuildKit. Refs CLC-2245. Co-authored-by: Ona <no-reply@ona.com>

Description
Bumps the pinned buildkit base image used by
components/image-builder-bob:dockerfromv0.20.1-gitpod.6tov0.20.1-gitpod.7, which rebases on Alpine 3.23 and Go 1.26.2.This clears the two critical CVEs that the daily scheduled
Buildworkflow'sCheck for Critical Vulnerabilitiesstep has been failing on:libssl3/libcrypto33.5.5-r0go1.22.4(in moby/buildkit)Verified locally with grype: the new image has zero critical Alpine apk vulnerabilities. The remaining stdlib Critical findings (CVE-2025-22871, CVE-2026-27143, CVE-2025-68121) only show up in the legacy
buildkit-cni-*plugin binaries, which Leeway's vulnerability rollup does not include in the failing-package count — i.e. the same scope as before, minus the two we set out to fix.Related Issue(s)
