Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU6304

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-4907

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in VMware Unified Access Gateway and Horizon View. A remote attacker can trigger heap-based buffer overflow and execute arbitrary code on security gateway.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

The vulnerability is fixed in Unified Access Gateway (formerly Access Point) 2.8.1, Horizon View 7.1.0 and 6.2.4.

Vulnerable software versions

VMware Horizon: 6.2 - 7.0.3

VMWare Unified Access Gateway: 2.8.0
