CVE-2018-11793: Apache Mesos

High severity, CVSS 7.5. EPSS: 5% chance of exploitation in the next 30 days.

When parsing a JSON payload with deeply nested JSON structures, the parser in Apache Mesos versions pre-1.4.x, 1.4.0 to 1.4.2, 1.5.0 to 1.5.1, 1.6.0 to 1.6.1, and 1.7.0 might overflow the stack due to unbounded recursion. 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 1.4.3 (fixed in 1.4.3); from 1.5.0, before 1.5.2 (fixed in 1.5.2); from 1.6.0, before 1.6.2 (fixed in 1.6.2); from 1.7.0, before 1.7.1 (fixed in 1.7.1); version 1.4.0 only; version 1.8.0 only
