FreeBSD Security Advisory - Kernel Memory Disclosure
Posted Jul 9, 2014
Site security.freebsd.org

FreeBSD Security Advisory - 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.
