There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The eap_pwd_process function in eap_server/eap_server_pwd.c in hostapd 2.x before 2.6 does not validate
    that the reassembly buffer is large enough for the final fragment when used with (1) an internal EAP
    server or (2) a RADIUS server and EAP-pwd is enabled in a runtime configuration, which allows remote
    attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd
    message. (CVE-2015-5314)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2808-1 advisory.

    It was discovered that wpa_supplicant incorrectly handled WMM Sleep Mode Response frame processing. A     remote attacker could use this issue to perform broadcast/multicast packet injections, or cause a denial     of service. (CVE-2015-5310)

    It was discovered that wpa_supplicant and hostapd incorrectly handled certain EAP-pwd messages. A remote     attacker could use this issue to cause a denial of service. (CVE-2015-5314, CVE-2015-5315)

    It was discovered that wpa_supplicant incorrectly handled certain EAP-pwd Confirm messages. A remote     attacker could use this issue to cause a denial of service. This issue only applied to Ubuntu 15.10.
    (CVE-2015-5316)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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