CVE-2023-29319

Memory disclosure via unchecked QXD decoding bounds

Published Jul 12, 2023 · Updated Mar 5, 2025

Out-of-bounds read in Adobe InDesign 18.3 and earlier and 17.4.1 and earlier allows attackers to disclose memory via a crafted QXD file. The affected QXD-decoding plugin fails to validate bounds before reading from a malformed QuarkXPress Drawing file. Exploitation requires a victim to open the file, exposing sensitive process memory that can assist an ASLR bypass, without reported data modification or service interruption.
