Descriptions

Adobe Photoshop CC versions 19.1.8 and earlier and 20.0.5 and earlier have an out of bound write vulnerability. Successful exploitation could lead to arbitrary code execution.

Las versiones 19.1.8 y anteriores de Adobe Photoshop CC y 20.0.5 y versiones anteriores tienen una vulnerabilidad de escritura fuera de ella. La explotación exitosa podría conducir a la ejecución arbitraria de código.

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 processing of the drop command in PostScript. 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 buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
