CVE-2024-6638
An integer overflow vulnerability due to improper input validation when reading TDMS files in LabVIEW may result in an infinite loop.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
Description
An integer overflow vulnerability due to improper input validation when reading TDMS files in LabVIEW may result in an infinite loop. Successful exploitation requires an attacker to provide a user with a specially crafted TDMS file. This vulnerability affects LabVIEW 2024 Q1 and prior versions.
