Updated 10.06.2020
Updated description, links and remediation section for vulnerabilities #1-3
Added vulnerability #4
1) Untrusted Pointer Dereference
EUVDB-ID: #VU28019
Risk: Low
CVSSv3.1: 6.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-0915
CWE-ID:
CWE-822 - Untrusted Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to untrusted pointer dereference within the user-mode printer driver host process splwow64.exe within the Windows Graphics Device Interface (GDI). A local user can run a specially crafted program to trigger untrusted pointer dereference and execute arbitrary code on the system with elevated privileges in the context of the current user at medium integrity level.
Successful exploitation of the vulnerability requires that attacker has the ability to execute low-privileged code on the target system.

2) Untrusted Pointer Dereference
EUVDB-ID: #VU28018
Risk: Low
CVSSv3.1: 6.7 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:H/RL:O/RC:C]
CVE-ID: CVE-2020-0986
CWE-ID:
CWE-822 - Untrusted Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to untrusted pointer dereference within the user-mode printer driver host process splwow64.exe within the Windows kernel. A local user can run a specially crafted program to trigger untrusted pointer dereference and execute arbitrary code on the system with elevated privileges in the context of the current user at medium integrity level.
Successful exploitation of the vulnerability requires that attacker has the ability to execute low-privileged code on the target system.
