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
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.

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
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.
