## What is CVE-2023-24511?

CVE-2023-24511 is a medium-severity denial of service vulnerability in Arista Networks EOS, published on 12 Apr 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

On affected platforms running Arista EOS with SNMP configured, a specially crafted packet can cause a memory leak in the snmpd process.

Check this codebase for CVE-2023-24511 and fix it if it is affected.

What it is: CVE-2023-24511 is a medium-severity denial of service vulnerability in Arista Networks EOS, published on 12 Apr 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 CVE-2023-24511 in the wild and no public exploit code.

Affected product: Arista Networks EOS. 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.
