Detail

A vulnerability in the Open Container Initiative runc CLI tool used by multiple products could allow an unauthenticated, remote attacker to escalate privileges on a targeted system.

The vulnerability exists because the affected software improperly handles file descriptors related to /proc/self/exe. An attacker could exploit the vulnerability either by persuading a user to create a new container using an attacker-controlled image or by using the docker exec command to attach into an existing container that the attacker already has write access to. A successful exploit could allow the attacker to overwrite the host's runc binary file with a malicious file, escape the container, and execute arbitrary commands with root privileges on the host system.

This advisory will be updated as additional information becomes available.
