Security Advisory

1) Buffer overflow

Severity: Low

CVSSv3: 6.1 [CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2019-1173

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Description

The vulnerability allows a local user to escalate privilege so the system.

The vulnerability exists due to a boundary error in the PsmServiceExtHost.dll when handling objects in memory. A local user can create a specially crafted application, trigger memory corruption and execute arbitrary code on the target system with elevated privileges.

Mitigation

Install update from vendor's website.
