The remote Ubuntu host is missing one or more security-related

Description :

An information leak was discovered in the Linux kernel when built with
the NetFilter Connection Tracking (NF_CONNTRACK) support for IRC
protocol (NF_NAT_IRC). A remote attacker could exploit this flaw to
obtain potentially sensitive kernel information when communicating
over a client- to-client IRC connection(/dcc) via a NAT-ed network.

Matthew Thode reported a denial of service vulnerability in the Linux
kernel when SELinux support is enabled. A local user with the
CAP_MAC_ADMIN capability (and the SELinux mac_admin permission if
running in enforcing mode) could exploit this flaw to cause a denial
of service (kernel crash). (CVE-2014-1874)

An information leak was discovered in the Linux kernel's NFS
filesystem. A local users with write access to an NFS share could
exploit this flaw to obtain potential sensative information from
kernel memory. (CVE-2014-2038).
