is 5.x (with local mode) prior to 5.4.2. It is, therefore, affected by
a privilege escalation vulnerability due to a failure to provide a
valid discretionary access control list (DACL) pointer for the
printproxy.exe process. A local attacker, using thread injection, can
exploit this to gain elevated privileges or execute arbitrary code.");
