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.

Antti Levomaki, Christian Jalio, and Joonas Pihlaja discovered that Wget incorrectly handled certain HTTP responses. A remote attacker could use this issue to cause Wget to crash, resulting in a denial of service, or possibly execute arbitrary code. Dawid Golunski discovered that Wget incorrectly handled recursive or mirroring mode. A remote attacker could possibly use this issue to bypass intended access list restrictions. Various other issues were also addressed.
