Security Bulletin
This security bulletin contains one high risk vulnerability.
1) Buffer overflow
EUVDB-ID: #VU39309
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-2017-2775
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
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.
MitigationInstall update from vendor's website.
Vulnerable software versionsLabVIEW: 16.0.0.49152
