Descriptions

Race condition in wget 1.17 and earlier, when used in recursive or mirroring mode to download a single file, might allow remote servers to bypass intended access list restrictions by keeping an HTTP connection open.

Condición de carrera en wget1.17 y versiones anteriores, cuando es utilizado en modo recursivo o de reflejo para descargar un único archivo, podría permitir a servidores remotos eludir las restricciones de lista destinadas al acceso manteniendo una conexión HTTP abierta.

GNU wget versions 1.17 and earlier, when used in mirroring/recursive mode, are affected by a race condition vulnerability that might allow remote attackers to bypass intended wget access list restrictions specified with the -A parameter. This might allow attackers to place malicious/restricted files onto the system. Depending on the application / download directory, this could potentially lead to other vulnerabilities such as code execution, etc.
