Which packages are affected by CVE-2017-12174?

CVE-2017-12174 affects the following packages: org.hornetq:hornetq-server (Maven), org.apache.activemq:artemis-native (Maven). Ecosystems affected: Maven.

How do I fix CVE-2017-12174?

Update org.hornetq:hornetq-server to 2.4.0.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-12174 is resolved across your whole dependency graph.

How do I detect CVE-2017-12174 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.hornetq:hornetq-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2017-12174 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is CVE-2017-12174 actively exploited in the wild?

No public exploit code has been indexed for CVE-2017-12174 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

It was found that when Artemis and HornetQ before 2.4.0 are configured with UDP discovery and JGroups discovery a huge byte array is created when receiving an unexpected multicast message. This may result in a heap memory exhaustion, full GC, or OutOfMemoryError.
