CVE-2023-47076

Application crash via malicious file NULL dereference

Published Dec 13, 2023 · Updated Nov 25, 2024

NULL pointer dereference in Adobe InDesign 19.0 and earlier and 17.4.2 and earlier allows attackers to crash the application via a malicious file. Adobe has not disclosed the parser, file structure, or invalid value that reaches the NULL dereference, so the faulty operation is not public. Exploitation requires a victim to open the crafted file and interrupts only that user's InDesign process.
