## What is CVE-2009-4997?

CVE-2009-4997 is a high-severity vulnerability in n/a, published on 7 Sep 2010. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

gnome-power-manager 2.27.92 does not properly implement the lock_on_suspend and lock_on_hibernate settings for locking the screen when the suspend or hibernate button is pressed, which might make it easier for physically proximate attackers to access an unattended laptop via a resume action, a related issue to CVE-2010-2532.  NOTE: this issue exists because of a regression that followed a gnome-power-manager fix a few years earlier.

Weakness: CWE-264

Check this codebase for CVE-2009-4997 and fix it if it is affected.

What it is: CVE-2009-4997 is a high-severity vulnerability in n/a, published on 7 Sep 2010. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2009-4997 in the wild and no public exploit code.

Affected product: n/a. 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.
