Synopsis:          Important: kernel security and bug fix update
Advisory ID:       SLSA-2018:2846-1
Issue Date:        2018-10-09
CVE Numbers:       CVE-2018-14634
                   CVE-2018-5391
--

Security Fix(es):

* A flaw named FragmentSmack was found in the way the Linux kernel handled
reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could
use this flaw to trigger time and calculation expensive fragment
reassembly algorithm by sending specially crafted packets which could lead
to a CPU saturation and hence a denial of service on the system.
(CVE-2018-5391)

* kernel: Integer overflow in Linux's create_elf_tables function
(CVE-2018-14634)
