script_tag(name: "insight", value: "A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems.  This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module.  This  action is usually restricted to root-priveledged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS. (CVE-2016-4997 )An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments. (CVE-2016-4998 )A vulnerability was found in the Linux kernel. The pointer to the netlink socket attribute is not checked, which could cause a null pointer dereference when parsing the nested attributes in function tipc_nl_publ_dump(). This allows local users to cause a DoS. (CVE-2016-4951 )(Updated 2016-07-14: CVE-2016-4998  and CVE-2016-4951  were fixed in this version, but was not previously listed in this errata.)");
