Descriptions

Adobe Acrobat Reader versions 23.003.20244 (and earlier) and 20.005.30467 (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 file.

Las versiones 23.003.20244 (y anteriores) y 20.005.30467 (y anteriores) de Adobe Acrobat Reader están afectadas por una vulnerabilidad de lectura fuera de los límites que podría provocar la ejecución de código arbitrario 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 Acrobat Reader DC. 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 embedded fonts. 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 object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
