## What is CVE-2012-0655?

CVE-2012-0655 is a medium-severity vulnerability in Apple Mac Os X, published on 11 May 2012. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

libsecurity in Apple Mac OS X before 10.7.4 does not properly restrict the length of RSA keys within X.509 certificates, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by conducting a spoofing or network-sniffing attack during communication with a site that uses a short key.

Weakness: CWE-310

## Which versions are affected by CVE-2012-0655?

It affects 2 products.


Products: Apple Mac Os X, Apple Mac Os X Server.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2012-0655 and fix it if it is affected.

What it is: CVE-2012-0655 is a medium-severity vulnerability in Apple Mac Os X, published on 11 May 2012. 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-2012-0655 in the wild and no public exploit code.

Affected product: Apple Mac Os X. 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.
