Description
The Notary Project is a set of specifications and tools intended to provide a cross-industry standard for securing software supply chains by using authentic container images and other OCI artifacts. An external actor with control of a compromised container registry can provide outdated versions of OCI artifacts, such as Images. This could lead artifact consumers with relaxed trust policies (such as permissive instead of strict) to potentially use artifacts with signatures that are no longer valid, making them susceptible to any exploits those artifacts may contain. In Notary Project, an artifact publisher can control the validity period of artifact by specifying signature expiry during the signing process. Using shorter signature validity periods along with processes to periodically resign artifacts, allows artifact producers to ensure that their consumers will only receive up-to-date artifacts. Artifact consumers should correspondingly use a strict or equivalent trust policy that enforces signature expiry. Together these steps enable use of up-to-date artifacts and safeguard against rollback attack in the event of registry compromise. The Notary Project offers various signature validation options such as permissive, audit and skip to support various scenarios. These scenarios includes 1) situations demanding urgent workload deployment, necessitating the bypassing of expired or revoked signatures; 2) auditing of artifacts lacking signatures without interrupting workload; and 3) skipping of verification for specific images that might have undergone validation through alternative mechanisms. Additionally, the Notary Project supports revocation to ensure the signature freshness. Artifact publishers can sign with short-lived certificates and revoke older certificates when necessary. This revocation serves as a signal to inform artifact consumers that the corresponding unexpired artifact is no longer approved by the publisher. This enables the artifact publisher to control the validity of the signature independently of their ability to manage artifacts in a compromised registry.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/notaryproject/notation. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/notaryproject/notation has shipped for CVE-2024-23332 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2024-23332 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-23332. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
