Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
1) Privilege escalation
EUVDB-ID: #VU975
Risk: Medium
CVSSv3.1: 8.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:U/RC:C]
CVE-ID: CVE-2016-7182
CWE-ID:
CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to boundary error in the Microsoft Windows kernel-mode driver (Win32k). By running a malicious program on the affected system attackers can execute arbitrary code with SYSTEM privileges.
Successful exploitation of the vulnerability may result in a complete system compromise.
MitigationInstall update from vendor's website.

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.
How the attacker can exploit this vulnerability?
The attacker would have to trick the victim to visit a specially crafted website or open a file.
The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Arbitrary code execution
EUVDB-ID: #VU963
Risk: Critical
CVSSv3.1: 9.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:H/RL:U/RC:C]
CVE-ID: CVE-2016-3393
CWE-ID:
CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Graphics Device Interface (GDI) component. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
Note: the vulnerability was being actively exploited.

3) Memory corruption
EUVDB-ID: #VU965
Risk: High
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2016-3396
CWE-ID:
CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Graphics Device Interface (GDI) component. A remote attacker can create a specially crafted content containing embedded fonts, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

4) Information disclosure
EUVDB-ID: #VU959
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-2016-3209
CWE-ID:
CWE-401 - Improper Release of Memory Before Removing Last Reference ('Memory Leak')
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to boundary error in the Graphics Device Interface (GDI) component. A local attacker can execute a specially crafted program on the affected system, get information about system memory state, bypass Address Space Layout Randomization (ASLR) and conduct further attacks.
Successful exploitation of the vulnerability will result in information disclosure on the vulnerable system.
