ALBA-2021:3594 libdb bug fix and enhancement update
Not scored
Published
Check this codebase for ALBA-2021:3594 and fix it if it is affected.
What it is: ALBA-2021:3594 is a denial of service vulnerability in libdb, published on 21 Sep 2021.
Exploitation: There is no known exploitation of ALBA-2021:3594 in the wild and no public exploit code.
Affected product: libdb. 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.
