Descriptions

Adobe Photoshop CC 2019 versions 20.0.8 and earlier, and Photoshop 2020 versions 21.1 and earlier have a buffer errors vulnerability. Successful exploitation could lead to arbitrary code execution.

Adobe Photoshop CC 2019 versiones 20.0.8 y anteriores, y Photoshop 2020 versiones 21.1 y anteriores, presentan una vulnerabilidad de errores del búfer. Una explotación con éxito podría conllevar a una ejecución de código arbitraria.

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 PCX files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
