CVE-2024-43760

Code execution via unchecked JP2 parser write

Published Sep 13, 2024 · Updated Sep 18, 2024

Out-of-bounds write in Adobe Photoshop 24.7.4 and 25.11 and earlier allows remote attackers to execute code via a crafted JP2 file. The JP2 parser inadequately validates file data, allowing a crafted value to drive a write past the end of an allocated object. A victim must open the file or visit a malicious page; successful exploitation runs code in the Photoshop process and current-user context.
