Subject: [CVE-2017-9799] Apache Storm Possible Code Execution As A Different

Severity: High

Vendor: The Apache Software Foundation

Versions Affected:
Apache Storm 1.0.0, 1.0.1, 1.0.2, 1.0.3
Apache Storm 1.1.0

It was found that under some situations and configurations of storm it is theoretically possible for the owner of a topology to trick the supervisor to launch a worker as a different, non-root, user. In the worst case this could lead to secure credentials of the other user being compromised.  This vulnerability only applies to Apache Storm installations with security components enabled.

Users of the affected versions should apply one of the following mitigations:

- Upgrade to Apache Storm 1.0.4 or later
- Upgrade to Apache Storm 1.1.1 or later

Apache Storm 1.1.1 and 1.0.4 can be downloaded here:

This issue was identified by the Apche Storm PMC
