1) Heap-based buffer overflow

EUVDB-ID: #VU6537

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-2017-2797

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

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

The weakness exists due to heap-based buffer overflow in the ParseEnvironment functionality when parsing malicious .ppt files. A remote attacker can send a specially crafted .ppt file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.

Successful exploitation of this vulnerability may result in system compromise.

Mitigation

Update to version 8.0-6.4.
