  symbolic links. This could potentially allow an attacker to execute malicious code on
  the user's device and thereby take over the system. It also allowed an attacker to read
  data and files on the system such as the /etc/shadow file.

  The local code execution vulnerability was resolved by not allowing symbolic links to be
  followed on SMB and AFP shares. Permission changes were also made to the /etc/shadow
  file to prevent unprivileged users from accessing it.");
