Subject: CVE-2017-9790: Libprocess might crash when decoding an HTTP request
 with absent path.

Severity: Important

The Apache Software Foundation

Versions Affected:
Apache Mesos 1.1.0 to 1.3.0
The unsupported Apache Mesos 1.0.x as well as 0.x versions may be also

When handling a libprocess message wrapped in an HTTP request, libprocess
crashes if the request path is empty, because the parser assumes the request
path always starts with '/'. A malicious actor can therefore cause a denial
of service of Mesos masters rendering the Mesos-controlled cluster

pre-1.1.x users should upgrade to at least 1.1.3
1.1.x users should upgrade to 1.1.3
1.2.x users should upgrade to 1.2.2
1.3.0 users should upgrade to 1.3.1
1.4.0-dev users should obtain Mesos 1.4.0

This issue was discovered by Lyon Yang and Jeremy Heng

Alex on behalf of Mesos PMC
