Descriptions

FreeBSD 8.4 before p14, 9.1 before p17, 9.2 before p10, and 10.0 before p7 does not properly initialize the buffer between the header and data of a control message, which allows local users to obtain sensitive information from kernel memory via unspecified vectors.

FreeBSD 8.4 anterior a p14, 9.1 anterior a p17, 9.2 anterior a p10 y 10.0 anterior a p7 no inicializa debidamente el buffer entre la cabecera y los datos de un mensaje de control, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de vectores no especificados.

The control message API is used to construct ancillary data objects for use in control messages sent and received across sockets and passed via the recvmsg(2) and sendmsg(2) system calls. Buffer between control message header and data may not be completely initialized before being copied to userland. Three SCTP cmsgs, SCTP_SNDRCV, SCTP_EXTRCV and SCTP_RCVINFO, have implicit padding that may not be completely initialized before being copied to userland. In addition, three SCTP notifications, SCTP_PEER_ADDR_CHANGE, SCTP_REMOTE_ERROR and SCTP_AUTHENTICATION_EVENT, have padding in the returning data structure that may not be completely initialized before being copied to userland.
