DESCRIPTION

* CVE-2017-7645: Remote denial-of-service via overly sized NFS2/3 RPC call.

If an NFS version 2 or 3 client appends extraneous data to their RPC
calls or replies, the server fails to correctly allocate sufficient
memory, potentially causing memory corruption and a denial-of-service.


* CVE-2017-7477: Remote Denial-of-service in 802.1AE implementation.

A flaw in the handling of memory allocation in the macsec driver can
result in a buffer overflow.  A remote attacker could use this flaw to
cause a denial-of-service.
