Descriptions

Adobe Photoshop CC versions 19.1.8 and earlier and 20.0.5 and earlier have an out of bound read vulnerability. Successful exploitation could lead to memory leak.

Adobe Photoshop CC versiones 19.1.8 y anteriores y 20.0.5 y anteriores tienen una vulnerabilidad de lectura fuera de límite. La explotación exitosa podría conducir a una pérdida de memoria.

This vulnerability allows remote attackers to disclose sensitive information 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 index 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 read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
