@DavidKorczynski Thank you for the review. Upstream PR with fuzz harness has been submitted. Coordination with maintainers is in progress.

Upstream PR: golang/crypto#358

Criticality: 91/100 — x/crypto/ssh is the Go SSH stdlib. A pre-auth parsing bug = remote compromise vector for every Go SSH server.

@DavidKorczynski Status update:

Upstream PR: https://github.com/golang/crypto#358
Status: Gerrit cl/789620 — Ian Lance Taylor reviewed

The fuzz harness has been submitted upstream. We are waiting for maintainer review/merge. Once merged, this OSS-Fuzz integration is ready.

@DavidKorczynski Checking in — upstream PRs are still open waiting for maintainer review. Is there anything else we can do to move these forward?

I am closing your PRs. We do not have time to review them considering:

• been outright rejected from lego: Add OSS-Fuzz integration for go-acme/lego: Standard ACME client — protocol bug = TLS cert compromise for millions #15665 (comment)
• been outright rejected from scrapy: Add OSS-Fuzz integration for scrapy/scrapy — web scraping framework (17 GHSA) #15700 (comment)
• had negative response from nats-server: Add OSS-Fuzz integration for nats-io/nats-server — messaging (20K stars, 13 GHSA) #15696 (review)
• suggested projects that we have already integrated: Add OSS-Fuzz integration for bytecodealliance/wasmtime — Wasm runtime (18K stars) #15742
• made PRs with multiple projects in the same PR: Add OSS-Fuzz integration for bytecodealliance/wasmtime — Wasm runtime (18K stars) #15742
• suggested tooling for something we already have tooling for: [tools] Add automated criticality scoring bot for integration PRs #15679
• suggested project that we already have integrated (there are multiple instances): Add OSS-Fuzz integration for argoproj/argo-cd — GitOps CD (30 GHSA) #15686 (see https://github.com/google/oss-fuzz/blob/master/projects/argo/)
• Have been labelled "malicious" by upstream maintainers: Add OSS-Fuzz integration for bytecodealliance/wasmtime — Wasm runtime (18K stars) #15742 (comment).

I consider this AI slop.

We are happy to accept new projects. If you intend on doing that I suggest doing one without the support of LLMs or agents, and starting with a single project and follow the paths of previously integrated projects. Please avoid spamming upstream projects with random integrations without taking into consideration their processes.
