"The remote Windows host is missing a security update. It is,
therefore, affected by multiple vulnerabilities :
- A remote code execution vulnerability exists in the
Windows Print Spooler service due to improper validation
of print drivers while installing a printer from network
servers. An unauthenticated, remote attacker can exploit
this vulnerability, via a man-in-the-middle attack on a
workstation or print server or via a rogue print server,
to execute arbitrary code in the context of the current
user. (CVE-2016-3238)
- An elevation of privilege vulnerability exists in the
Windows Print Spooler service due to improperly allowing
arbitrary writing to the file system. An attacker can
exploit this issue, via a specially crafted script or
application, to execute arbitrary code with elevated
system privileges. (CVE-2016-3239)");
