ArchLinux: 201708-17: salt: directory traversal
Summary
It has been discovered that maliciously crafted minion IDs can cause unwanted directory traversals on the salt-master. The flaw is within the minion id validation which could allow certain minions to authenticate to a master despite not having the correct credentials. To exploit the vulnerability, an attacker must create a salt-minion with an ID containing characters that will cause a directory traversal.
Resolution
Upgrade to 2017.7.1-1.
# pacman -Syu "salt>=2017.7.1-1"
The problem has been fixed upstream in version 2017.7.1.
