Improper Input Validation
A specifically crafted Docker image running under the root user can overwrite the init helper binary of the container runtime and/or the command executor in Apache Mesos. A malicious actor can therefore gain root-level code execution on the host.

Containment Errors (Container Errors)
runc allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to `/proc/self/exe`.

Improper Input Validation
When parsing a malformed JSON payload, libprocess in Apache Mesos crashes due to an uncaught exception. Parsing chunked HTTP requests with trailers can lead to a libprocess crash because of the mistakenly planted assertion.

Improper Restriction of Operations within the Bounds of a Memory Buffer
When parsing a JSON payload with deeply nested JSON structures, the parser in Apache Mesos might overflow the stack due to unbounded recursion.

Information Exposure
Apache Mesos can be configured to require authentication to call the Executor HTTP API using JSON Web Token (JWT). In Apache Mesos, the comparison of the generated HMAC value against the provided signature in the JWT implementation used is vulnerable to a timing attack.
