CVE-2020-28926

Estado: ModificadaCrítica (9.8)—

ReadyMedia (aka MiniDLNA) before versions 1.3.0 allows remote code execution. Sending a malicious UPnP HTTP request to the miniDLNA service using HTTP chunked encoding can lead to a signedness bug resulting in a buffer overflow in calls to memcpy/memmove.
