Information disclosure in Microsoft Windows Kernel

1) Information disclosure

EUVDB-ID: #VU8769

Risk: Low

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-11765

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists due to an error when the Windows kernel handles objects in memory. A local attacker can run a specially crafted application and gain access to arbitrary data.

Successful exploitation of the vulnerability may result in further attack.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Windows: 7 - 10

Windows Server: 2008 - 2016 10.0.14393.10

3) Information disclosure

EUVDB-ID: #VU8771

Risk: Low

CVSSv3.1: 5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2017-11785

CWE-ID: CWE-200 - Information exposure

Exploit availability: Yes

Description

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to an error when the Windows kernel handles objects in memory. A local attacker can run a specially crafted application, retrieve the memory address of a kernel object and bypass Kernel Address Space Layout Randomization (ASLR).

Successful exploitation of the vulnerability may result in further attack.

Mitigation

Install updates from vendor's website.
