Code execution via malformed CGF import
Published Jun 11, 2021 · Updated Aug 3, 2024
Out-of-bounds write in IGSS Definition 15.0.0.21140 and earlier allows attackers to execute code after a malicious CGF file is imported. Def.exe fails to validate user-supplied CGF data before writing it, causing an out-of-bounds memory write during import. Exploitation requires local user interaction with the crafted file and can execute code or destroy data in the IGSS process context.
