CVE-2022-42717: Improper Privilege Management

October 11, 2022 (updated October 14, 2022)

An issue was discovered in Hashicorp Packer before 2.3.1. The recommended sudoers configuration for Vagrant on Linux is insecure. If the host has been configured according to this documentation, non-privileged users on the host can leverage a wildcard in the sudoers configuration to execute arbitrary commands as root.
