Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

The discovered vulnerabilities allow a remote attacker to obtain potentially sensitive information and execute arbitrary code on vulnerable system.

1) Memory Corruption in Graphics Component

EUVDB-ID: #VU299

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-3318

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

Exploit availability: No

Description

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

The vulnerability exists due to boundary error when parsing objects in memory within Graphics Component. A remote attacker can create a specially crafted Office document, convince the victim to open it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of this vulnerability may allow an attacker to run arbitrary code on vulnerable system.
