Descriptions

Adobe After Effects version 18.2.1 (and earlier) is affected by an Out-of-bounds Read vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to disclose sensitive memory information in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Adobe After Effects versiones 18.2.1 (y anteriores), está afectada por una vulnerabilidad de lectura fuera de límites cuando se analiza un archivo especialmente diseñado. Un atacante no autenticado podría aprovechar esta vulnerabilidad para divulgar información confidencial de la memoria en el contexto del usuario actual. Es requerida una interacción del usuario para explotar este problema, ya que la víctima debe abrir un archivo malicioso

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Adobe After Effects. 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 PDF 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 arbitrary code in the context of the current process.
