CVE-2019-0204

Vulnerability

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. Affected versions include all versions before 1.4.x, 1.4.0 through 1.4.2, 1.5.0 through 1.5.2, 1.6.0 through 1.6.1, and 1.7.0 through 1.7.1 [1][2].

Exploitation

An attacker must be able to run a Docker image as the root user within a Mesos task. By crafting a malicious Docker image that overwrites the init helper binary or command executor, the attacker can execute arbitrary code when the container runtime initializes or executes commands [2].

Impact

Successful exploitation allows the attacker to gain root-level code execution on the host system, leading to full compromise of the host [1][2].

Mitigation

Red Hat published an advisory (RHSA-2019:3892) with a fix for affected Red Hat products. For Apache Mesos, the vulnerability is fixed in versions 1.4.3, 1.5.3, 1.6.2, and 1.7.2. Users should upgrade to these or later versions [1].
