Descriptions

Adobe After Effects versions 22.0 (and earlier) and 18.4.2 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Las versiones 22.0 (y anteriores) y 18.4.2 (y anteriores) de Adobe After Effects se ven afectadas por una vulnerabilidad de lectura fuera de los límites que podría provocar la divulgación de memoria sensible. Un atacante podría aprovechar esta vulnerabilidad para evitar mitigaciones como ASLR. La explotación de este problema requiere la interacción del usuario, 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 MP4 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.
