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.

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

This vulnerability allows 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 charstring store commands in font definitions within PostScript 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 buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
