github.com/cri-o/cri-o is vulnerable to Privilege Escalation. The vulnerability exists because the setupContainerUser function in container_create.go does not properly validate the homedir parameter, allowing an attacker to maliciously craft an environment variable with newlines to add entries to a container’s /etc/passwd.
