Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

When handling a decoding failure for a malformed URL path of an HTTP request, libprocess in Apache Mesos before 1.1.3, 1.2.x before 1.2.2, 1.3.x before 1.3.1, and 1.4.0-dev might crash because the code accidentally calls inappropriate function. A malicious actor can therefore cause a denial of service of Mesos masters rendering the Mesos-controlled cluster inoperable.
