Upgrade ansible-jailexec to version 2.0.0 or higher.
Overview
ansible-jailexec is an Ansible connection plugin for FreeBSD jails via jexec over SSH
Affected versions of this package are vulnerable to Symlink Attack via the put_file process. An attacker can perform arbitrary root-owned file writes on the host system by placing a symbolic link inside the jail at or above the destination path before the file transfer occurs. This is only exploitable if the operator runs a copy/template/fetch-style task against the jail and the attacker has the ability to create a symlink in a directory that will be written to by an Ansible task.
