CVE-2023-29309

Memory disclosure via malformed QXD file decoding

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 QXD file. The QuarkXPress Drawing decoder omits a bounds check when processing a malformed QXD file and reads beyond the intended memory boundary. Exploitation requires a victim to open the file, exposing sensitive process memory and helping attackers bypass ASLR.
