CVE-2012-2333 Integer overflow in n/a
Medium 6.8
Published

Check this codebase for CVE-2012-2333 and fix it if it is affected.
What it is: CVE-2012-2333 is a medium-severity vulnerability in Openssl Openssl, published on 14 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-2012-2333 in the wild and no public exploit code.
Affected product: Openssl Openssl. 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.

What is CVE-2012-2333?
CVE-2012-2333 is a medium-severity vulnerability in Openssl Openssl, published on 14 May 2012. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1 before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted TLS packet that is not properly handled during a certain explicit IV calculation.
Weakness: CWE-189
