CVE-2023-26356

Memory disclosure via USD buffer over-read

Published Mar 28, 2023 · Updated Mar 5, 2025

Out-of-bounds read in Adobe Dimension 3.4.7 and earlier allows context-dependent attackers to disclose memory through a crafted USD file. Dimension reads past the end of an allocated buffer while parsing crafted data in the file. Exploitation requires a victim to open the file; disclosure can reveal process memory and weaken ASLR, while code execution requires another flaw.
