(CVE-2016-3135 )In the mark_source_chains function (net/ipv4/netfilter/ip_tables.c) it is possible for a user-supplied ipt_entry structure to have a large next_offset field. This field is not bounds checked prior to writing a counter value at the supplied offset. (CVE-2016-3134 )A weakness was found in the Linux ASLR implementation. Any user able to run 32-bit applications in a x86 machine can disable the ASLR by setting the RLIMIT_STACK resource to unlimited. (CVE-2016-3672 )Destroying a network interface with a large number of IPv4 addresses keeps a rtnl_lock for a very long time, which can block many network-related operations. (CVE-2016-3156 )");
