CVE-2023-26370

Arbitrary code execution via uninitialized PSD parser memory

Published Oct 11, 2023 · Updated Aug 2, 2024

Code execution in Adobe Photoshop 23.5.5 and earlier and 24.7 and earlier allows attackers to run code when a user opens a malicious PSD file. The PSD parser accesses memory before properly initializing it, allowing attacker-controlled file data to influence execution. Opening the crafted file is required, and successful exploitation runs code with the current user's privileges.
