## Fix prompt for AI coding agents

```text
Check this codebase for CVE-1999-0041 and fix it if it is affected.

What it is: CVE-1999-0041 is a high-severity memory corruption vulnerability in Ibm Aix, published on 29 Sep 1999. 
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-1999-0041 exists.

Affected product: Ibm Aix. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
