## What is CVE-2016-9592?

CVE-2016-9592 is a medium-severity denial of service vulnerability in Redhat Openshift, published on 16 Apr 2018. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

openshift before versions 3.3.1.11, 3.2.1.23, 3.4 is vulnerable to a flaw when a volume fails to detach, which causes the delete operation to fail with 'VolumeInUse' error. Since the delete operation is retried every 30 seconds for each volume, this could lead to a denial of service attack as the number of API requests being sent to the cloud-provider exceeds the API's rate-limit.

Weakness: CWE-399, CWE-460 (Improper Cleanup on Thrown Exception)

Check this codebase for CVE-2016-9592 and fix it if it is affected.

What it is: CVE-2016-9592 is a medium-severity denial of service vulnerability in Redhat Openshift, published on 16 Apr 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2016-9592 in the wild and no public exploit code.

Affected product: Redhat Openshift. 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.
