The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wpa_supplicant: local configuration update allows privilege escalation (CVE-2016-4477)

  - hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject \n and \r characters in     passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a     crafted WPS operation. (CVE-2016-4476)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Jouni Malinen reports :

psk configuration parameter update allowing arbitrary data to be written (2016-1 - CVE-2016-4476/CVE-2016-4477).

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wpa_supplicant: local configuration update allows privilege escalation (CVE-2016-4477)

  - wpa_supplicant: Reinstallation of the pairwise key in the 4-way handshake (CVE-2017-13077)

  - NetworkManager 0.9 and earlier allows local users to use other users' certificates or private keys when     making a connection via the file path when adding a new connection. (CVE-2012-1096)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

A vulnerability was found in how hostapd and wpa_supplicant writes the configuration file update for the WPA/WPA2 passphrase parameter. If this parameter has been updated to include control characters either through a WPS operation (CVE-2016-4476) or through local configuration change over the wpa_supplicant control interface (CVE-2016-4477), the resulting configuration file may prevent the hostapd and wpa_supplicant from starting when the updated file is used. In addition for wpa_supplicant, it may be possible to load a local library file and execute code from there with the same privileges under which the wpa_supplicant process runs.

CVE-2016-4476 hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject \n and \r characters in passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a crafted WPS operation.

CVE-2016-4477 wpa_supplicant 0.4.0 through 2.5 does not reject \n and \r characters in passphrase parameters, which allows local users to trigger arbitrary library loading and consequently gain privileges, or cause a denial of service (daemon outage), via a crafted (1) SET, (2) SET_CRED, or (3) SET_NETWORK command.

For Debian 7 'Wheezy', these problems have been fixed in version 1.0-3+deb7u4.

We recommend that you upgrade your wpa packages.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - NetworkManager, wpa_supplicant: Improper x509v3 certificate and key file paths sanitization     (CVE-2012-1096)

  - wpa_supplicant: local configuration update allows privilege escalation (CVE-2016-4477)

  - hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject \n and \r characters in     passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a     crafted WPS operation. (CVE-2016-4476)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3455-1 advisory.

    Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly handled WPA2. A remote attacker could     use this issue with key reinstallation attacks to obtain sensitive information. (CVE-2017-13077,     CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081, CVE-2017-13082, CVE-2017-13086,     CVE-2017-13087, CVE-2017-13088)

    Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase     parameters. A remote attacker could use this issue to cause a denial of service. (CVE-2016-4476)

    Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase     parameters. A local attacker could use this issue to cause a denial of service, or possibly execute     arbitrary code. (CVE-2016-4477)

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.
