On systems where the strcpy function is implemented with memcpy, the de_dotdot function may cause a Denial-of-Service (daemon crash) due to overlapping memory ranges being passed to memcpy. This can triggered with an HTTP GET request for a crafted filename. NOTE: this is similar to CVE-2017-10671, but occurs in a different part of the de_dotdot function."

En los sistemas en los que la funci\u00f3n strcpy es implementada con memcpy, la funci\u00f3n de_dotdot puede causar una denegaci\u00f3n de servicio (bloqueo del demonio) debido a la superposici\u00f3n de rangos de memoria que se pasan a memcpy. Esto puede desencadenar con una petici\u00f3n HTTP GET para un nombre de archivo dise\u00f1ado.
