Adobe Photoshop versions 21.2.10 (and earlier) and 22.4.3 (and earlier) are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Adobe Photoshop versiones 21.2.10 (y anteriores), y 22.4.3 (y anteriores), están afectadas por una vulnerabilidad de escritura fuera de límites que podría resultar en la ejecución de código arbitrario en el contexto del usuario actual. Es requerida una interacción del usuario para explotar este problema, ya que la víctima debe abrir un archivo malicioso

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Adobe Photoshop. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of U3D files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process.
