Update to version 2.8 from upstream, Security fix for [CVE-2019-11555]

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the wpa_supplicant package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - hostapd before 2.10 and wpa_supplicant before 2.10     allow an incorrect indication of disconnection in     certain situations because source address validation is     mishandled. This is a denial of service that should     have been prevented by PMF (aka management frame     protection). The attacker must send a crafted 802.11     frame from a location that is within the 802.11     communications range.(CVE-2019-16275)

  - The EAP-pwd implementation in hostapd (EAP server)     before 2.8 and wpa_supplicant (EAP peer) before 2.8     does not validate fragmentation reassembly state     properly for a case where an unexpected fragment could     be received. This could result in process termination     due to a NULL pointer dereference (denial of service).
    This affects eap_server/eap_server_pwd.c and     eap_peer/eap_pwd.c.(CVE-2019-11555)

  - The implementations of EAP-PWD in wpa_supplicant EAP     Peer, when built against a crypto library missing     explicit validation on imported elements, do not     validate the scalar and element values in     EAP-pwd-Commit. An attacker may complete     authentication, session key and control of the data     connection with a client. Both hostapd with SAE support     and wpa_supplicant with SAE support prior to and     including version 2.4 are affected. Both hostapd with     EAP-pwd support and wpa_supplicant with EAP-pwd support     prior to and including version 2.7 are     affected.(CVE-2019-9499)

  - The implementations of EAP-PWD in hostapd EAP Server,     when built against a crypto library missing explicit     validation on imported elements, do not validate the     scalar and element values in EAP-pwd-Commit. An     attacker may be able to use invalid scalar/element     values to complete authentication, gaining session key     and network access without needing or learning the     password. Both hostapd with SAE support and     wpa_supplicant with SAE support prior to and including     version 2.4 are affected. Both hostapd with EAP-pwd     support and wpa_supplicant with EAP-pwd support prior     to and including version 2.7 are     affected.(CVE-2019-9498)

  - The implementations of EAP-PWD in hostapd EAP Server     and wpa_supplicant EAP Peer do not validate the scalar     and element values in EAP-pwd-Commit. This     vulnerability may allow an attacker to complete EAP-PWD     authentication without knowing the password. However,     unless the crypto library does not implement additional     checks for the EC point, the attacker will not be able     to derive the session key or complete the key exchange.
    Both hostapd with SAE support and wpa_supplicant with     SAE support prior to and including version 2.4 are     affected. Both hostapd with EAP-pwd support and     wpa_supplicant with EAP-pwd support prior to and     including version 2.7 are affected.(CVE-2019-9497)

Several vulnerabilities were discovered in WPA supplicant / hostapd.
Some of them could only partially be mitigated, please read below for details.

CVE-2019-9495

Cache-based side-channel attack against the EAP-pwd implementation: an attacker able to run unprivileged code on the target machine (including for example JavaScript code in a browser on a smartphone) during the handshake could deduce enough information to discover the password in a dictionary attack.

This issue has only very partially been mitigated against by reducing measurable timing differences during private key operations. More work is required to fully mitigate this vulnerability.

CVE-2019-9497

Reflection attack against EAP-pwd server implementation: a lack of validation of received scalar and elements value in the EAP-pwd-Commit messages could have resulted in attacks that would have been able to complete EAP-pwd authentication exchange without the attacker having to know the password. This did not result in the attacker being able to derive the session key, complete the following key exchange and access the network.

CVE-2019-9498

EAP-pwd server missing commit validation for scalar/element: hostapd didn't validate values received in the EAP-pwd-Commit message, so an attacker could have used a specially crafted commit message to manipulate the exchange in order for hostapd to derive a session key from a limited set of possible values. This could have resulted in an attacker being able to complete authentication and gain access to the network.

This issue could only partially be mitigated.

CVE-2019-9499

EAP-pwd peer missing commit validation for scalar/element:
wpa_supplicant didn't validate values received in the EAP-pwd-Commit message, so an attacker could have used a specially crafted commit message to manipulate the exchange in order for wpa_supplicant to derive a session key from a limited set of possible values. This could have resulted in an attacker being able to complete authentication and operate as a rogue AP.

This issue could only partially be mitigated.

CVE-2019-11555

The EAP-pwd implementation did't properly validate fragmentation reassembly state when receiving an unexpected fragment. This could have lead to a process crash due to a NULL pointer derefrence.

An attacker in radio range of a station or access point with EAP-pwd support could cause a crash of the relevant process (wpa_supplicant or hostapd), ensuring a denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 2.3-1+deb8u8.

We recommend that you upgrade your wpa packages.
