Description |
|
|
Se ha descubierto una vulnerabilidad en libcurl y curl desde la versión 7.11.2 hasta la 7.15.0. La vulnerabilidad reside en la función de manejo de URL que desborda un búfer. Un atacante local podría elevar privilegios o saltarse los mecanismos de protección del modo seguro de PHP (safe_mode/ open_basedir). También existe la posibilidad de que un atacante remoto puediera ejecutar código arbitrario aunque es improbable ya que el ataque no puede ser lanzado por redirecciones HTTP. |
