CVE-2024-10496

Code execution via unchecked BuildFontMap input

Published Dec 10, 2024 · Updated Dec 10, 2024

Out-of-bounds read in LabVIEW 2024 Q3 and earlier allows local users to execute code or disclose data through a crafted VI file. BuildFontMap in fontmgr.cpp fails to validate an input index or offset before reading font-map data beyond the intended buffer. Exploitation requires a user to open the crafted VI, after which code execution or memory disclosure occurs in that user's LabVIEW context.
