CVE-2023-29274

Code execution via unvalidated USDC object read

Published May 11, 2023 · Updated Mar 5, 2025

Out-of-bounds read in Adobe Substance 3D Painter 8.3.0 and earlier allows remote attackers to execute code via a crafted USDC file. The USDC parser fails to validate user-supplied data before reading an allocated object, causing a read past the object's end. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current process and user context.
