CVE-2022-43448

Code execution via crafted image parsing

Published Jan 3, 2023 · Updated Apr 10, 2025

Out-of-bounds write in Fuji Electric V-SFT 6.1.7.0 and earlier and TELLUS 4.0.12.0 and earlier allows local users to execute code. The image-file handling code writes outside a valid memory buffer while processing crafted image data; public advisories do not identify the format, function, or malformed field. Exploitation requires a user to open the crafted file, after which attacker-controlled code runs in the affected application's context and process memory can be exposed.
