Descriptions

Adobe Photoshop CC 2019 versions 20.0.8 and earlier, and Photoshop 2020 versions 21.1 and earlier have an out-of-bounds write 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 escritura fuera de límites. 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 GIF 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.
