Reviewed by: Claude (automated)

Changes

Digest update in docker-compose.yml and docker-compose-dev.yml:
96d56f7 → 1b1689b (postgres:18-alpine)

Upstream analysis

The new digest pulls in two upstream changes:

1. PostgreSQL 18.3 → 18.4 (released May 14, 2026) — maintenance release with 12 security CVE fixes, including:

   • CVE-2026-6479: Unbounded recursion in startup packet processing
   • CVE-2026-6473: Integer overflows in memory allocation (potential arbitrary code execution)
   • CVE-2026-6476 / CVE-2026-6638 / CVE-2026-6637: SQL injection in pg_createsubscriber, logical replication, and contrib/spi
   • CVE-2026-6475: Path traversal in pg_basebackup / pg_rewind
   • CVE-2026-6477: Buffer overflow in PQfn()
   • Plus fixes for timing-safe auth comparisons, MCV stats validation, collation handling, and more.
   • Numerous non-security bug fixes (query planning, generated columns, replication, backup/recovery).
   • No breaking changes identified. No dump/restore required.

2. Alpine 3.22 → 3.24 — base OS version bump; no Dockerfile-level functional changes.

Security review (REVIEW.md)

• PII / secrets in diff: No — changes are limited to image digest hashes.
• Upstream regressions: None identified. This is a straightforward security maintenance release.

Verdict: Clean. This is a beneficial security update and safe to merge.

Upstream release notes (per REVIEW.md)

This PR bumps the postgres:18-alpine image digest. The new digest most likely includes PostgreSQL 18.4 (released May 14, 2026), which is a maintenance release with 12 security fixes (CVEs), including:

• CVE-2026-6473 — Multiple integer overflows in memory allocation (could lead to arbitrary code execution)
• CVE-2026-6479 — Unbounded recursion in startup packets that could crash backends
• CVE-2026-6474 — Buffer overflows in timeofday() and pg_strftime() via malicious timezone names
• CVE-2026-6475 — Path traversal in pg_basebackup and pg_rewind
• CVE-2026-6638 — SQL injection in logical replication origin checks
• CVE-2026-6476 — SQL injection via unquoted subscription names in pg_createsubscriber
• CVE-2026-6472 — Missing privilege checks on multirange type creation
• CVE-2026-6478 — Non-timing-safe password comparisons in authentication
• CVE-2026-6477 — Buffer overflow in PQfn() (deprecated)
• CVE-2026-6637 — SQL injection and buffer overruns in contrib/spi

Notable bug fixes include race condition fixes in WAL replay, walsender shutdown improvements, and visibility map persistence during recovery.

No regressions expected — this is a standard patch release. No dump/restore is required for users already on 18.x. The security fixes make this a recommended update.

Dependency Bump Review — postgres:18-alpine digest update

Reviewed the upstream changes for the digest bump 96d56f7 → 1b1689b.

What changed upstream

This digest bump pulls in two updates:

1. PostgreSQL 18.4 (released May 14, 2026) — a security and bug-fix release
2. Alpine 3.24 base image (up from 3.22)

Security fixes (11 CVEs)

PostgreSQL 18.4 addresses the following CVEs:

CVE	Summary
CVE-2026-6479	Unbounded recursion in startup packets — malicious client crash
CVE-2026-6473	Integer overflows in memory allocation (buffer overflows, potential code execution)
CVE-2026-6476	SQL injection in pg_createsubscriber
CVE-2026-6638	SQL injection in logical replication origin checks
CVE-2026-6474	Malicious time zone names causing crashes or memory disclosure
CVE-2026-6472	Missing privilege check on multirange types
CVE-2026-6478	Timing-safe string comparisons in authentication
CVE-2026-6477	PQfn() buffer overflow risk (now deprecated)
CVE-2026-6475	Path traversal in pg_basebackup / pg_rewind
CVE-2026-6637	SQL injection in contrib/spi check_foreign_key()
CVE-2026-6575	Faulty input in attribute MCV statistics restoration

Notable bug fixes relevant to PeerDB

• Replication fixes: slotsync worker blocking standby promotion, walsender shutdown hangs, excessive slotsync logging, free space map persistence during recovery, visibility map bloating during incremental backup restore, pg_stat_replication premature NULL lag reporting
• Query correctness: nondeterministic collation handling, array_agg combining with null bitmaps, generated column fixes
• Stability: parallel btree scan memory under-allocation, DSA page map sizing, multixact array indexing, pglz decompression buffer overread

Regression risk

• PQfn() deprecation: Not used by PeerDB — no impact.
• Foreign key deferrability fix: Only affects keys toggled between ENFORCED/NOT ENFORCED — unlikely to affect PeerDB's catalog schema.
• Collation behavior changes: Results are now more correct — no negative regression expected.

Verdict

No regressions identified. This is a security-critical update with 11 CVE fixes. The diff is limited to digest hash changes in docker-compose.yml and docker-compose-dev.yml. No PII or secret exposure. Safe to merge.

What changed upstream

This digest bump brings two updates:

1. PostgreSQL 18.3 → 18.4 (released May 14, 2026) — a maintenance release with 12 CVE fixes and many bug fixes:

   • CVE-2026-6479: Unbounded recursion from malicious SSL/GSS requests (crash)
   • CVE-2026-6473: Integer overflows in memory allocation → buffer overflow / arbitrary code execution
   • CVE-2026-6476 / CVE-2026-6638: SQL injection in pg_createsubscriber and logical replication origin checks

   • Plus fixes for replication (stuck slotsync workers, walsender shutdown), backup (incremental restore, LZ4 corruption), query planning, and contrib modules.
   • Updated timezone data to tzdata 2026b.
   • No breaking changes or regressions reported. No dump/restore required from 18.x.

2. Alpine 3.22 → 3.24 (released June 9, 2026) — the 18-alpine tag now resolves to 18/alpine3.24 after 3.22 was dropped upstream on June 10.

Diff review

• Only two files changed: docker-compose.yml and docker-compose-dev.yml, each updating a single image digest line.
• No PII or secret exposure concerns.
• No code logic changes.

Verdict

Clean bump. The security fixes in 18.4 make this update worthwhile. No regressions identified.

No concerns — the change is limited to Docker image digest strings. No logging, stdout, or stderr changes.

Upstream changes in bumped range

This digest bump likely brings PostgreSQL 18.3/18.4 security and bug fixes on Alpine 3.23:

PostgreSQL 18.4 (May 2026) — 12 CVEs fixed:

• Unbounded recursion in SSL/GSS startup (CVE-2026-6479)
• Integer overflows in memory allocation (CVE-2026-6473)
• SQL injection in pg_createsubscriber and ALTER SUBSCRIPTION (CVE-2026-6476, CVE-2026-6638)
• Buffer overflows in pg_basebackup and pg_rewind (CVE-2026-6475, CVE-2026-6477)
• Additional privilege check and timing-safe comparison fixes

PostgreSQL 18.3 (Feb 2026) — out-of-cycle regression fix:

• Fixed standby server crash on transaction status access
• Fixed substring() encoding errors on multi-byte text (regression from 18.2 CVE fix)
• Fixed pg_trgm strict_word_similarity crashes
• Fixed PL/pgSQL composite-type domain casting crashes

Alpine 3.23.4 (Apr 2026):

• OpenSSL patches (6 CVEs), musl fixes, zlib vulnerability fixes

Regression risk

No regressions identified that would affect PeerDB's catalog usage. The 18.3 out-of-cycle release specifically fixes regressions that were introduced in 18.2, so this bump lands on a stable point.

Verdict: Safe to merge. The bump brings significant security hardening with no expected impact on PeerDB.

What's in the new digest

The upstream postgres:18-alpine image has been rebuilt with:

• PostgreSQL 18.4 (released 2026-05-14) — includes 13 security CVE fixes (CVE-2026-6472 through CVE-2026-6638), covering unbounded recursion in startup packets, integer overflows in memory allocation, SQL injection in pg_createsubscriber and logical replication, buffer overflows in ts_headline(), path traversal in pg_basebackup/pg_rewind, timing-safe password comparisons, and more. No dump/restore required when upgrading from prior 18.x versions.
• Alpine 3.24 (released 2026-06-09) — base OS update with component bumps (LLVM 22, Rust 1.96, Go 1.26, etc.). Breaking changes in Alpine 3.24 (Python setuptools pkg_resources removal, GTK+ 2/3 and libsoup 2 removals) are not relevant to a PostgreSQL container.
• Alpine data-mount fix (2026-04-21) — fixed missing /var/lib/postgresql/data mounts in Alpine images.

Regression assessment

• PostgreSQL 18.4 release notes explicitly state no breaking changes and no dump/restore needed from 18.x.
• Alpine 3.24 breaking changes do not affect PostgreSQL container operation.
• No PII or secret exposure in the diff.

No issues found — safe to merge.
