1) Buffer overflow (CVE-ID: CVE-2019-1284)

CWE-ID: CWE-119 - Memory corruption

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way Windows handles objects in memory. A local user can create a malicious application, launch it on the system and run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would first have to log on to the system.


Remediation

Install update from vendor's website.
