CVE-2024-11477

7-Zip Zstandard Decompression Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the implementation of Zstandard decompression. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24346.

Summary		(es) Vulnerabilidad de ejecución remota de código por desbordamiento de enteros en la descompresión Zstandard de 7-Zip. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de 7-Zip. Se requiere la interacción con esta librería para explotar esta vulnerabilidad, pero los vectores de ataque pueden variar según la implementación. La falla específica existe dentro de la implementación de la descompresión Zstandard. El problema es el resultado de la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un desbordamiento de enteros antes de escribir en la memoria. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-24346.
