Memory disclosure via uninitialized USDC parser state
Published Apr 12, 2023 · Updated Mar 5, 2025
Uninitialized-pointer access in Adobe Substance 3D Stager 2.0.1 and earlier allows attackers to disclose sensitive process memory. The USDC parser accesses memory without properly initializing it, exposing residual data that can reveal addresses and weaken ASLR. Exploitation requires a victim to open a malicious file or visit a malicious page; the documented direct impact is information disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=unspecified <=2.0.1
- Affected versionversion=unspecified <=None
