runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, 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.
CVE-2019-5736
Score elevated to 9.0 because EPSS predicts 99% probability of exploitation within the next 30 days (top 0.1% of all CVEs). NVD baseline CVSS 8.6 retained for reference. Confidence: see factors.
