Descripción |
|
|
Se ha descubierto una vulnerabilidad de condición de carrera en PHP 5.1.6 y anteriores. La vulnerabilidad reside en un error en la función "symlink()" . Esta vulnerabilidad podría permitir a un atacante local saltarse las restricciones de "open_basedir" usando una combinación de los comandos "symlink", "mkdir", y "unlink" para cambiar la ruta de acceso después de que se haya realizado la comprobación "open_basedir" y antes de que el archivo sea abierto por el sistema. |
