High (7.5) in apache mesos. EPSS 3.7% chance of exploitation in the next 30 days. Fixed in org.apache.mesos:mesos 1.6.0.
When parsing a malformed JSON payload, libprocess in Apache Mesos versions 1.4.0 to 1.5.0 might crash due to an uncaught exception. Parsing chunked HTTP requests with trailers can lead to a libprocess crash too because of the mistakenly planted assertion. A malicious actor can therefore cause a denial of service of Mesos masters rendering the Mesos-controlled cluster inoperable.
