Descriptions

Adobe After Effects versions 22.0 (and earlier) and 18.4.2 (and earlier) are affected by an out-of-bounds read vulnerability which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. 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 están afectadas por una vulnerabilidad de lectura fuera de los límites que podría provocar una lectura más allá del final de una estructura de memoria asignada. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual. La explotación de este problema requiere la interacción del usuario en el sentido de que una 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 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 buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
