## What is GHSA-3wxx-jxwc-mg39?

GHSA-3wxx-jxwc-mg39 is an use after free vulnerability in bottlerocket/update-operator, published on 9 Feb 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A double-free vulnerability exists in OpenSSL where it is possible to construct a malicious PEM file that has 0 bytes of payload data. This then points to data that has already been freed in memory which, when freed again, leads to a crash. Agents or clients compiled with OpenSSL may crash unexpectedly when parsing these PEM files. OpenSSL has been removed in bottlerocket/update-operator version 1.1.0 in favor of Rust-based TLS using rustls.

Check this codebase for GHSA-3wxx-jxwc-mg39 and fix it if it is affected.

What it is: GHSA-3wxx-jxwc-mg39 is an use after free vulnerability in bottlerocket/update-operator, published on 9 Feb 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-3wxx-jxwc-mg39 in the wild and no public exploit code.

Affected packages and fixed versions:
- bottlerocket/update-operator (crates.io): affected all versions; fixed in 1.1.0

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.
