colibrì v1.6.2 — security release

Fixes six privately-reported memory-safety issues, all reachable from attacker-controlled input (a malicious model file / config.json, or the kimi_k3 SERVE stdin). Every fix validates at the trust boundary — no behavioural change on well-formed models or requests.

Advisory Engine / file Class
GHSA-gf38-c8fx-ppvv kimi_k3.c (SERVE) unbounded max_tok → signed overflow → heap OOB write
GHSA-2qrj-xjmh-mv74 json.h (shared) object key without quote check → heap OOB read
GHSA-w696-h9p7-6rgc inkling.c (DMel audio) unvalidated mel_vocab_size/n_mel_bins → OOB read
GHSA-7654-r78q-vc3r deepseek_v4.c qk_rope_head_dim > index_head_dim → OOB read/write
GHSA-9gjf-272q-4vv4 deepseek_v4.c + DSpark global/sidecar tensors loaded without shape check → OOB read
GHSA-8p69-257x-6fp6 DSpark drafter MTP expert slab sized from expert 0 → heap overflow write

Tensor-shape checks require >= expected (not exact equality), so a legitimately padded official checkpoint is never false-rejected.

Consolidated in [#1018]. Thanks to the reporter for the detailed advisories and proofs.

Also in this release (merged since v1.6.1)

  • V4 serve telemetry: report the expert-matmul phase on the web dashboard (#890 / [#1005])
  • Assorted small fixes and dashboard/tooling improvements.

Note

The archive now packages c/v4_dsml.py (imported by the OpenAI server) — the first release since the DSML refactor needed it.

Upgrade recommended for anyone loading models from untrusted mirrors or bridging the kimi_k3 SERVE protocol to untrusted clients.
