The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2614-1 advisory.

  - include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5     uses an insufficiently large data type for certain extension data, which allows local users to cause a     denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension     loading, as demonstrated by configuring a PPTP tunnel in a NAT environment. (CVE-2014-9715)

  - Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR) response. (CVE-2015-2150)

  - arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not prevent the TS_COMPAT flag from     reaching a user-mode task, which might allow local users to bypass the seccomp or audit protection     mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an     attack against seccomp before 3.16. (CVE-2015-2830)

  - The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before     3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-     dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute     arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an     AF_ALG(aead) socket. (CVE-2015-3331)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
