denial of service (system crash) via (1) an application that made

crafted system calls or possibly (2) IPv4 traffic with invalid IP

options (bsc#1025013).

- CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in

the Linux kernel did not properly validate certain block-size data,

which allowed local users to cause a denial of service (overflow) or

possibly have unspecified other impact via crafted system calls

(bsc#1030575, bsc#1031660).
