Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the four-way handshake, allowing an attacker within radio range to spoof frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). There is an IGTK group key reloading vulnerability in the fourth handshake of the WPA2 wireless network. WPA2 is prone to multiple security weaknesses.
Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. Those vulnerabilities applies to both the access point
(implemented in hostapd) and the station (implemented in wpa_supplicant).
An attacker exploiting the vulnerabilities could force the vulnerable system to
reuse cryptographic session keys, enabling a range of cryptographic attacks
against the ciphers used in WPA1 and WPA2.
For the stable distribution (stretch), these problems have been fixed in
version 2:2.4-1+deb9u1.
For the testing distribution (buster), these problems have been fixed
in version 2:2.4-1.1.
For the unstable distribution (sid), these problems have been fixed in
version 2:2.4-1.1.
We recommend that you upgrade your wpa packages. ==========================================================================

For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
0. Revision history
v1.0 2017-10-17 Initial release.
v1.1 2017-10-19 Add patches for 10.x releases.
I.
hostapd and wpa_supplicant are implementations of user space daemon for
access points and wireless client that implements the WPA2 protocol.
II. Problem Description
A vulnerability was found in how a number of implementations can be
triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by
replaying a specific frame that is used to manage the keys.
III. Impact
Such reinstallation of the encryption key can result in two different
types of vulnerabilities: disabling replay protection and significantly
reducing the security of encryption to the point of allowing frames to
be decrypted or some parts of the keys to be determined by an attacker
depending on which cipher is used.
IV. Workaround
An updated version of wpa_supplicant is available in the FreeBSD Ports
Collection. Install version 2.6_2 or later of the
security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf
to use the new binary:
wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"
and restart networking.
An updated version of hostapd is available in the FreeBSD Ports
Collection. Install version 2.6_1 or later of the net/hostapd port/pkg.
Once installed, update /etc/rc.conf to use the new binary:
hostapd_program="/usr/local/sbin/hostapd"
and restart hostapd.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart the Wi-Fi network interfaces/hostapd or reboot the system.
2) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the i386 or amd64
platforms can be updated via the freebsd-update(8) utility:

Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse
Related entries in the VARIoT exploits database: VAR-E-201710-0481 |
CVSS V2: 5.8 CVSS V3: 8.1 Severity: HIGH |
Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11r allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the fast BSS transmission (FT) handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames. Wi-Fi Protected Access (WPA, more commonly WPA2) handshake traffic can be manipulated to induce nonce and session key reuse, resulting in key reinstallation by a wireless access point (AP) or client. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The PTK-TK encryption key reloading vulnerability exists when the WPA2 wireless network receives and processes the retransmitted fast BSS transition reassociation request. WPA2 is prone to multiple security weaknesses.
Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE-----

3. Description:
The wpa_supplicant packages contain an 802.1X Supplicant with support for
WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP authentication
methods. They implement key negotiation with a WPA Authenticator for client
stations and controls the roaming and IEEE 802.11 authentication and
association of the WLAN driver. A remote attacker within Wi-Fi range
could exploit these attacks to decrypt Wi-Fi traffic or possibly inject
forged Wi-Fi packets by manipulating cryptographic handshakes used by the
WPA2 protocol. (CVE-2017-13077, CVE-2017-13078, CVE-2017-13080,

For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
0. Revision history
v1.0 2017-10-17 Initial release.
v1.1 2017-10-19 Add patches for 10.x releases.
I.
hostapd and wpa_supplicant are implementations of user space daemon for
access points and wireless client that implements the WPA2 protocol.
II. Problem Description
A vulnerability was found in how a number of implementations can be
triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by
replaying a specific frame that is used to manage the keys.
III. Impact
Such reinstallation of the encryption key can result in two different
types of vulnerabilities: disabling replay protection and significantly
reducing the security of encryption to the point of allowing frames to
be decrypted or some parts of the keys to be determined by an attacker
depending on which cipher is used.
IV. Workaround
An updated version of wpa_supplicant is available in the FreeBSD Ports
Collection. Install version 2.6_2 or later of the
security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf
to use the new binary:
wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"
and restart networking.
An updated version of hostapd is available in the FreeBSD Ports
Collection. Install version 2.6_1 or later of the net/hostapd port/pkg.
Once installed, update /etc/rc.conf to use the new binary:
hostapd_program="/usr/local/sbin/hostapd"
and restart hostapd.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart the Wi-Fi network interfaces/hostapd or reboot the system.
2) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the i386 or amd64
platforms can be updated via the freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
Restart the Wi-Fi network interfaces/hostapd or reboot the system.
3) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
[FreeBSD 11.0-RELEASE, 11.1-RELEASE, and 11-STABLE]
# fetch https://security.FreeBSD.org/patches/SA-17:07/wpa-11.patch
# fetch https://security.FreeBSD.org/patches/SA-17:07/wpa-11.patch.asc

| VAR-201710-0208 | CVE-2017-13081 |
Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse
Related entries in the VARIoT exploits database: VAR-E-201710-0481 |
CVSS V2: 2.9 CVSS V3: 5.3 Severity: MEDIUM |
Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the group key handshake, allowing an attacker within radio range to spoof frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The IGTK group key reloading vulnerability exists in the WPA2 wireless network. WPA2 is prone to multiple security weaknesses.
Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. Those vulnerabilities applies to both the access point
(implemented in hostapd) and the station (implemented in wpa_supplicant).
An attacker exploiting the vulnerabilities could force the vulnerable system to
reuse cryptographic session keys, enabling a range of cryptographic attacks
against the ciphers used in WPA1 and WPA2.
For the stable distribution (stretch), these problems have been fixed in
version 2:2.4-1+deb9u1.
For the testing distribution (buster), these problems have been fixed

For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
0. Revision history
v1.0 2017-10-17 Initial release.
v1.1 2017-10-19 Add patches for 10.x releases.
I.
hostapd and wpa_supplicant are implementations of user space daemon for
access points and wireless client that implements the WPA2 protocol.
II. Problem Description
A vulnerability was found in how a number of implementations can be
triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by
replaying a specific frame that is used to manage the keys.
III. Impact
Such reinstallation of the encryption key can result in two different
types of vulnerabilities: disabling replay protection and significantly
reducing the security of encryption to the point of allowing frames to
be decrypted or some parts of the keys to be determined by an attacker
depending on which cipher is used.
IV. Workaround
An updated version of wpa_supplicant is available in the FreeBSD Ports
Collection. Install version 2.6_2 or later of the
security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf
to use the new binary:
wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"
and restart networking.
An updated version of hostapd is available in the FreeBSD Ports
Collection. Install version 2.6_1 or later of the net/hostapd port/pkg.
Once installed, update /etc/rc.conf to use the new binary:
hostapd_program="/usr/local/sbin/hostapd"
and restart hostapd.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart the Wi-Fi network interfaces/hostapd or reboot the system.
2) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the i386 or amd64
platforms can be updated via the freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
Restart the Wi-Fi network interfaces/hostapd or reboot the system.
3) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
[FreeBSD 11.0-RELEASE, 11.1-RELEASE, and 11-STABLE]
# fetch https://security.FreeBSD.org/patches/SA-17:07/wpa-11.patch

| VAR-201710-0211 | CVE-2017-13078 |
Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse
Related entries in the VARIoT exploits database: VAR-E-201710-0481 |
CVSS V2: 2.9 CVSS V3: 5.3 Severity: MEDIUM |
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the four-way handshake, allowing an attacker within radio range to replay frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The WPA2 wireless network has a GTK group key reload vulnerability in the fourth handshake. WPA2 is prone to multiple security weaknesses.
Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE-----

0. Revision history
v1.0 2017-10-17 Initial release.
v1.1 2017-10-19 Add patches for 10.x releases.
I.
hostapd and wpa_supplicant are implementations of user space daemon for
access points and wireless client that implements the WPA2 protocol.
II. Problem Description
A vulnerability was found in how a number of implementations can be
triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by
replaying a specific frame that is used to manage the keys.
III. Impact
Such reinstallation of the encryption key can result in two different
types of vulnerabilities: disabling replay protection and significantly
reducing the security of encryption to the point of allowing frames to
be decrypted or some parts of the keys to be determined by an attacker
depending on which cipher is used.
IV. Workaround
An updated version of wpa_supplicant is available in the FreeBSD Ports
Collection. Install version 2.6_2 or later of the
security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf
to use the new binary:
wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"
and restart networking.
An updated version of hostapd is available in the FreeBSD Ports
Collection. Install version 2.6_1 or later of the net/hostapd port/pkg.
Once installed, update /etc/rc.conf to use the new binary:
hostapd_program="/usr/local/sbin/hostapd"
and restart hostapd.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart the Wi-Fi network interfaces/hostapd or reboot the system.
2) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the i386 or amd64
platforms can be updated via the freebsd-update(8) utility:

| VAR-201710-0206 | CVE-2017-13077 |
Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse
Related entries in the VARIoT exploits database: VAR-E-201710-0481 |
CVSS V2: 5.4 CVSS V3: 6.8 Severity: MEDIUM |
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The WPA2 wireless network has a PTK-TK key reload vulnerability in the fourth handshake. WPA2 is prone to multiple security weaknesses.
Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information. -----BEGIN PGP SIGNED MESSAGE-----

0. Revision history
v1.0 2017-10-17 Initial release.
v1.1 2017-10-19 Add patches for 10.x releases.
I.
hostapd and wpa_supplicant are implementations of user space daemon for
access points and wireless client that implements the WPA2 protocol.
II. Problem Description
A vulnerability was found in how a number of implementations can be
triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by
replaying a specific frame that is used to manage the keys.
III. Impact
Such reinstallation of the encryption key can result in two different
types of vulnerabilities: disabling replay protection and significantly
reducing the security of encryption to the point of allowing frames to
be decrypted or some parts of the keys to be determined by an attacker
depending on which cipher is used.
IV. Workaround
An updated version of wpa_supplicant is available in the FreeBSD Ports
Collection. Install version 2.6_2 or later of the
security/wpa_supplicant port/pkg. Once installed, update /etc/rc.conf
to use the new binary:
wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"
and restart networking.
An updated version of hostapd is available in the FreeBSD Ports
Collection. Install version 2.6_1 or later of the net/hostapd port/pkg.
Once installed, update /etc/rc.conf to use the new binary:
hostapd_program="/usr/local/sbin/hostapd"
and restart hostapd.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart the Wi-Fi network interfaces/hostapd or reboot the system.

| VAR-201710-0207 | CVE-2017-13080 |
Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse
Related entries in the VARIoT exploits database: VAR-E-201710-0481 |
CVSS V2: 2.9 CVSS V3: 5.3 Severity: MEDIUM |
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection, TCP connection hijacking, HTTP content injection, or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or "KRACK" attacks. WPA (Wi-Fi Protected Access) is a system that protects wireless computer networks (Wi-Fi). The GTK group key reloading vulnerability exists in the WPA2 wireless network. WPA2 is prone to multiple security weaknesses.
Exploiting these issues may allow an unauthorized user to intercept and manipulate data or disclose sensitive information.
CVE-2017-13804: @qwertyoruiopz at KJC Research Intl. S.R.L.
CVE-2017-13080: Mathy Vanhoef of the imec-DistriNet group at KU
Leuven
Installation note:
Firmware version 7.6.9 is installed on AirPort Express, AirPort
Extreme, or AirPort Time Capsule base stations with 802.11n using
AirPort Utility for Mac or iOS.
AirPort Utility for Mac is a free download from
https://support.apple.com/downloads/ and AirPort Utility for iOS
is a free download from the App Store. Those vulnerabilities applies to both the access point
(implemented in hostapd) and the station (implemented in wpa_supplicant).
An attacker exploiting the vulnerabilities could force the vulnerable system to
reuse cryptographic session keys, enabling a range of cryptographic attacks
against the ciphers used in WPA1 and WPA2.
For the stable distribution (stretch), these problems have been fixed in
version 2:2.4-1+deb9u1.
For the testing distribution (buster), these problems have been fixed
in version 2:2.4-1.1.
For the unstable distribution (sid), these problems have been fixed in
version 2:2.4-1.1.
We recommend that you upgrade your wpa packages.
