## What is CVE-2023-29723?

CVE-2023-29723 is a high-severity denial of service vulnerability in n/a, published on 1 Jun 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Glitter Unicorn Wallpaper app for Android 7.0 thru 8.0 allows unauthorized applications to actively request permission to insert data into the database that records information about a user's personal preferences and will be loaded into memory to be read and used when the application is opened. By injecting data, the attacker can force the application to load malicious image URLs and display them in the UI. As the amount of data increases, it will eventually cause the application to trigger an OOM error and crash, resulting in a persistent denial of service attack.

Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-29723 exists.

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.
