Heap-memory disclosure via LZW-compressed semantic masks
Published Jun 16, 2026 · Updated Jun 16, 2026
Out-of-bounds read in Adobe DNG SDK 1.7.1 build 2536 and earlier allows context-dependent attackers to disclose heap memory via a DNG file. When rendering an LZW-compressed semantic mask through MaskedRGBTables, the SDK reads beyond the mask buffer and incorporates adjacent heap bytes into rendered output. A victim must open the malicious file in a consuming application, and the demonstrated consequence is memory disclosure without code execution or data modification.

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.
