DESCRIPTION

* 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.


* CVE-2014-0181: Incorrect namespace permission check in netlink sockets.

The kernel uses an incorrect set of permissions when querying netlink sockets
from different namespaces, allowing unprivileged users to disclose information
about networking in privileged namespaces.


* 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.
