Subject: CVE-2014-0101 -- Linux kernel: net: sctp: null pointer dereference
when processing authenticated cookie_echo chunk
A flaw was found in the way Linux kernel processed authenticated
COOKIE_ECHO chunks.
A remote attacker could use this flaw to crash the system by sending a
maliciously prepared SCTP handshake in order to trigger a NULL pointer
dereference on the server.
