Esto puede suceder al finalizar la compra (DirCacheCheckout), fusionar (ResolveMerger a trav\u00e9s de su WorkingTreeUpdater), extraer (PullCommand usando merge) y al aplicar un parche (PatchApplier). Esto se puede aprovechar para la ejecuci\u00f3n remota de c\u00f3digo (RCE), por ejemplo, si el archivo escrito fuera del \u00e1rbol de trabajo es un filtro git que se ejecuta en un comando git posterior. El problema ocurre solo en sistemas de archivos que no distinguen entre may\u00fasculas y min\u00fasculas, como los sistemas de archivos predeterminados en Windows y macOS. El usuario que realiza la clonaci\u00f3n o el pago debe tener derechos para crear enlaces simb\u00f3licos para que ocurra el problema, y ??los enlaces simb\u00f3licos deben estar habilitados en la configuraci\u00f3n de git.
