Local denial of service in Microsoft Windows

1) Buffer overflow

EUVDB-ID: #VU22712

Risk: Low

CVSSv3.1: 4.2 [CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-12207

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the mechanism responsible for error handling on some Intel platforms. A local user of a guest operating system can use a specially crafted application to trigger memory corruption and cause the host system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.

2) Buffer overflow

EUVDB-ID: #VU22645

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-1391

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary error when Windows improperly handles objects in memory. A local user can use a specially crafted application to trigger memory corruption and cause the system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.

Mitigation
