## What is CVE-2023-23301?

CVE-2023-23301 is a critical memory corruption vulnerability in n/a, published on 23 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The `news` MonkeyC operation code in CIQ API version 1.0.0 through 4.1.7 fails to check that string resources are not extending past the end of the expected sections. A malicious CIQ application could craft a string that starts near the end of a section, and whose length extends past its end. Upon loading the string, the GarminOS TVM component may read out-of-bounds memory.

Weakness: CWE-125 (Out-of-bounds Read)

Check this codebase for CVE-2023-23301 and fix it if it is affected.

What it is: CVE-2023-23301 is a critical memory corruption vulnerability in n/a, published on 23 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-23301 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.
5. If nothing in the project is affected, say so and change nothing.
