Descriptions

Adobe InDesign versions 16.3 (and earlier), and 16.3.1 (and earlier) are affected by an out-of-bounds read vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious TIF file.

Adobe InDesign versiones 16.3 (y anteriores), y versiones 16.3.1 (y anteriores), están afectadas por una vulnerabilidad de lectura fuera de límites que podría resultar en una ejecución de código arbitrario en el contexto del usuario actual. Es requerida una interacción del usuario para explotar este problema, ya que la víctima debe abrir un archivo TIF malicioso

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Adobe InDesign. 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 parsing of TIF 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 structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
