Descripción

*** Pendiente de traducción *** After dispatching a decrypt operation to OCF and receiving the result, the wg(4) driver failed to check whether the MAC verification step succeeded. The driver thus silently accepted packets with an invalid Poly1305 authentication tag.<br /> <br /> A remote attacker who can send UDP packets to a WireGuard endpoint, and who can guess the bounds of the receiver&amp;#39;s replay window, can inject forged or modified transport data packets into the tunnel.<br /> <br /> A remote attacker who can intercept WireGuard packets bound for a FreeBSD host can modify the ciphertext and authenticated data without detection by the receiver.
