This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.\n\nThe specific flaw exists within the parsing of SQFS 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. Was ZDI-CAN-18589."

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de 7-Zip. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica existe en el análisis de archivos SQFS. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-18589."
