CVE-2018-1330
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.74%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
