DESCRIPTION

* CVE-2014-5077: Remote denial-of-service in SCTP on simultaneous connections.

Linux kernel built with the support for Stream Control Transmission
Protocol is vulnerable to a NULL pointer dereference flaw. It could occur
when simultaneous new connections are initiated between the same pair of
hosts. A remote user/program could use this flaw to crash the system kernel
resulting in denial-of-service.


* CVE-2014-4667: Denial-of-service in SCTP stack when unpacking a COOKIE_ECHO chunk.

Incorrect reference counting in the error path of sctp_unpack_cookie()
could corrupt the backlog reference counter, preventing any future SCTP
association. A remote attacker could use this flaw to cause a
denial-of-service.
