Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Privilege escalation

EUVDB-ID: #VU5061

Risk: Medium

CVSSv3.1: 8.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]

CVE-ID: CVE-2016-0167

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The vulnerability exists due to improper handling of objects in memory by the kernel-mode driver. A local attacker can run a specially crafted program, gain elevated privileges and execute arbitrary code with SYSTEM privileges.

Successful exploitation of this vulnerability may result in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Windows: 7 - Vista

Windows Server: 2008 - 2012 R2

CPE2.3 External links

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

Yes. This vulnerability is being exploited in the wild.

2) Privilege escalation

EUVDB-ID: #VU5060

Risk: Medium

3) Memory corruption

EUVDB-ID: #VU5059

Risk: High

CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2016-0145

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

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when handling of malicious embedded fonts. A remote attacker can create a specially crafted content, trick the victim into opening it, trigger memory corruption and execute arbitrary code.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Mitigation

Install update from vendor's website.
