Security Advisory

1) Privilege escalation

Severity: Medium

CVSSv3: 8.2 [CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C] [PCI]

CVE-ID: CVE-2016-0167

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

Exploit availability: Yes [Search exploit]

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, 8.1, 10, RT 8.1, Vista

Windows Server: 2008, 2008 R2, 2012, 2012 R2

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?

No. We are not aware of malware exploiting this vulnerability. However, a fully functional exploit for this vulnerability is available.

2) Privilege escalation

Severity: Medium

CVSSv3: 8.2 [CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C] [PCI]

3) Memory corruption

Severity: High

CVSSv3: 8.6 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C] [PCI]

CVE-ID: CVE-2016-0145

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

Exploit availability: Yes [Search exploit]

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.
