## What is CVE-2015-0245?

CVE-2015-0245 is a low-severity vulnerability in Opensuse Opensuse, published on 13 Feb 2015. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

D-Bus 1.4.x through 1.6.x before 1.6.30, 1.8.x before 1.8.16, and 1.9.x before 1.9.10 does not validate the source of ActivationFailure signals, which allows local users to cause a denial of service (activation failure error returned) by leveraging a race condition involving sending an ActivationFailure signal before systemd responds.

Weakness: CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2015-0245 and fix it if it is affected.

What it is: CVE-2015-0245 is a low-severity vulnerability in Opensuse Opensuse, published on 13 Feb 2015. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2015-0245 in the wild and no public exploit code.

Affected product: Opensuse Opensuse. 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.
