CVE-2018-1330: Apache Mesos

High severity, CVSS 7.5. EPSS: 3.7% chance of exploitation in the next 30 days.

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.

Affected products

• Apache Mesos: from 1.4.0, before 1.4.2 (fixed in 1.4.2); from 1.5.0, before 1.5.1 (fixed in 1.5.1); version 1.4.0 only; version 1.6.0 only
