Descriptions

After Effects version 18.0 (and earlier) are affected by an out-of-bounds write 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 file.

After Effects versiones 18.0 (y anteriores), está afectada por una vulnerabilidad de escritura fuera de límites que podría resultar en una ejecución de código arbitrario en el contexto del usuario actual. Una explotación de este problema requiere una interacción del usuario, en que la víctima debe abrir un archivo malicioso

This vulnerability allows remote attackers to execute arbitrary code 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 processing of embedded fonts in PDF 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.
