# CVE-2017-2775: An exploitable memory corruption vulnerability exists in the LvVariantUnflatten functionality in 64-bit versions of LabVIEW before 2015 SP1

- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
- Known exploited (CISA KEV): no
- Published: 2017-03-31 · Updated: 2024-08-05

## Affected

- National Instruments LabVIEW 2016 Evaluation: 16.0.0.49152

## Description

An exploitable memory corruption vulnerability exists in the LvVariantUnflatten functionality in 64-bit versions of LabVIEW before 2015 SP1 f7 Patch and 2016 before f2 Patch. A specially crafted VI file can cause a user controlled value to be used as a loop terminator resulting in internal heap corruption. An attacker controlled VI file can be used to trigger this vulnerability, exploitation could lead to remote code execution.

## What to do

- Check your stack: if you ship or depend on National Instruments LabVIEW 2016 Evaluation, no fixed version is listed yet; follow the vendor advisory per the references below.
