Description |
|
|
Se ha descubierto una vulnerabilidad en Unzip versión 5.51 y anteriores. La vulnerabilidad reside en que Unzip no alerta al usuario cuando se extraen ficheros con permisos setuid y setgid. Un atacante local podría elevar sus privilegios mediante un fichero zip que incluya un fichero ejecutable con permisos setuid y setgid. Existe una prueba de concepto disponible. |
