Backport CVE-2026-18618 fix: upgrade bundled gRPC/protobuf and fix upb builds on arm64/ppc64le - #26
Conversation
Bump gRPC to 1.58.3, protobuf to 23.4, Bazel to 6.3.2, and zlib to 1.3.1, with a ZetaSQL patch for protobuf 23 compatibility so filter_query keeps working. Install Bazel 6.3.2 in Konflux Dockerfile for .bazelversion pin Provide Bazel 6.3.2 binaries for COPR bazel wrapper on all Konflux arches Use community Bazel 6.3.2 binary for ppc64le Konflux builds Install aarch64 Bazel binary under name expected by COPR wrapper Suppress upb fortify-source false positives on ppc64le Bazel builds

📝 WalkthroughWalkthroughThe change sets Bazel 6.3.2 and upgrades several external dependencies, including gRPC 1.58.3 for CVE-2024-7246. It migrates protobuf generation to modern Bazel rules, updates well-known type dependencies, and removes legacy C++ API settings. It updates ZetaSQL protobuf compatibility checks and applies the patch. It adds architecture-specific Bazel installation and compiler flags to the Red Hat Dockerfile. The Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The current change cannot build until the WORKSPACE conflict is resolved. The container toolchain selection and supply-chain safeguards also need correction before merge. 🚥 Pre-merge checks | ✅ 10✅ Passed checks (10 passed)

Inline comments:
In `@ml_metadata/tools/docker_server/Dockerfile.redhat`:
- Line 49: Fix the WORKSPACE syntax causing Bazel to fail parsing before the
bazel build invocation runs. Update the invalid declaration or expression in
WORKSPACE so Bazel can load it successfully, while preserving the existing build
configuration and dependencies.
- Around line 35-36: Add verification of the downloaded Bazel artifact in the
Docker build before it is executable or used: validate it against an audited
per-architecture SHA-256 checksum or signature, then retain the existing
installation flow only after verification succeeds. Update the download block
around BAZEL_BIN and BAZEL_URL without changing unrelated build steps.
- Around line 35-36: The Dockerfile currently downloads Bazel to the
architecture-specific BAZEL_BIN path while build commands resolve /usr/bin/bazel
from the bazel5 package. Update the Bazel installation step to make the
downloaded Bazel 6.3.2 binary available as /usr/bin/bazel, or update build
invocations to use the downloaded BAZEL_BIN path, ensuring Bazel 6.3.2 is
selected.
In `@WORKSPACE`:
- Line 270: Remove the unresolved merge-conflict markers from WORKSPACE,
including the `<<<<<<< HEAD` marker and its corresponding separators, and retain
exactly one valid `ZETASQL_COMMIT` configuration block so Bazel can evaluate the
file.

Verify the Bazel artifact before installation (CWE-494).
${BAZEL_BIN} is downloaded into /usr/bin and later runs during bazel build as root. Add an audited per-architecture SHA-256 or signature check before installation.

Select the downloaded Bazel 6.3.2 binary. The bazel5 package provides /usr/bin/bazel, while the downloaded binary has an architecture-specific filename. The bazel build command therefore uses Bazel 5. Install the download as /usr/bin/bazel or invoke its absolute path.
