CVE-2017-11468 is a high-severity (CVSS 7.5) CWE-770 vulnerability in github.com/docker/distribution. O3 Security confirms whether CVE-2017-11468 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Docker Registry has Allocation of Resources Without Limits or Throttling
Real-World Exposure
github.com/docker/distributionReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Docker Registry before 2.6.2 in Docker Distribution does not properly restrict the amount of content accepted from a user, which allows remote attackers to cause a denial of service (memory consumption) via the manifest endpoint.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/docker/distribution | all versions | 2.7.0-rc.0 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/docker/distribution. 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.
Fix
Update github.com/docker/distribution to 2.7.0-rc.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-11468 is resolved across your whole dependency graph.
Workarounds
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-2017-11468 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-2017-11468. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2017-11468 in your dependencies?
O3 detects CVE-2017-11468 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
