Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Integrity Group Temporal Key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients. Wi-Fi Protected Access (WPA y WPA2) que soporte IEEE 802.11v permite la reinstalación de la clave temporal GTK (Integrity Group Temporal Key) cuando se procesa un frame Wireless Network Management (WNM) Sleep Mode Response, haciendo que un atacante que se sitúe dentro del radio reproduzca frames desde los puntos de acceso hasta los clientes. A new exploitation technique called key reinstallation attacks (KRACK) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used integrity group key (IGTK) during a Wireless Network Management (WNM) Sleep Mode handshake. • http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00024.html http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-007.txt http://www.debian.org/security/2017/dsa-3999 http://www.kb.cert.org/vuls/id/228519 http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.securityfocus.com/bid/101274 http • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-330: Use of Insufficiently Random Values •

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. Wi-Fi Protected Access (WPA y WPA2) permite la reinstalación de la clave temporal (TK) PTK (Pairwise Transient Key) durante la negociación en cuatro pasos, haciendo que un atacante que se sitúe entro del radio responda, descifre o suplante frames. A new exploitation technique called key reinstallation attacks (KRACKs) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used pairwise key (PTK-TK) during a 4-way handshake. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-007.txt http://www.debian.org/security/2017/dsa-3999 http://www.kb.cert.org/vuls/id/228519 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.securityfocus.com/bid/101274 http://www.securitytracker.com/id/1039573 http://www.securitytracker.com/id/1039576 http://www.securitytracker.com/id/1039577 http://www.security • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-330: Use of Insufficiently Random Values •

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. Wi-Fi Protected Access (WPA y WPA2) que soporte IEEE 802.11w permite la reinstalación de la clave temporal IGTK (Integrity Group Temporal Key) durante el handshake de clave de grupo, haciendo que un atacante en el rango de radio suplante frames desde los puntos de acceso hasta los clientes. • http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00024.html http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-007.txt http://www.debian.org/security/2017/dsa-3999 http://www.kb.cert.org/vuls/id/228519 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.securityfocus.com/bid/101274 http • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-330: Use of Insufficiently Random Values •

Multiple integer overflows in the NDEF record parser in hostapd before 2.5 and wpa_supplicant before 2.5 allow remote attackers to cause a denial of service (process crash or infinite loop) via a large payload length field value in an (1) WPS or (2) P2P NFC NDEF record, which triggers an out-of-bounds read. Múltiples desbordamientos de entero en el analizador de registro NDEF en hostapd en versiones anteriores a 2.5 y wpa_supplicant en versiones anteriores a 2.5 permite a atacantes remotos causar una denegación de servicio (caída de proceso o bucle infinito) a través de un valor de campo payload length grande en un registro (1) WPS o (2) P2P NFC NDEF, lo que desencadena una lectura fuera de rangos. • http://lists.opensuse.org/opensuse-updates/2015-11/msg00037.html http://lists.opensuse.org/opensuse-updates/2015-11/msg00041.html http://w1.fi/security/2015-5/incomplete-wps-and-p2p-nfc-ndef-record-payload-length-validation.txt http://www.debian.org/security/2015/dsa-3397 http://www.openwall.com/lists/oss-security/2015/11/02/5 http://www.securityfocus.com/bid/75604 https://w1.fi/cgit/hostap/plain/hostapd/ChangeLog https://w1.fi/cgit/hostap/plain/wpa_supplicant/ChangeLog • CWE-189: Numeric Errors •

Heap-based buffer overflow in the eap_server_tls_process_fragment function in eap_server_tls_common.c in the EAP authentication server in hostapd 0.6 through 1.0 allows remote attackers to cause a denial of service (crash or abort) via a small "TLS Message Length" value in an EAP-TLS message with the "More Fragments" flag set. Desbordamiento de búfer basado en memoria dinámica en la función eap_server_tls_process_fragment de eap_server_tls_common.c en el servidor de autenticación EAP en hostapd v0.6 hasta v1.0 permite a atacantes remotos provocar un denegación de servicio (caída o cancelación) mediante un valor "TLS Message Length" pequeño, en un mensaje EAP-TLS con el valor "More Fragments" activo. • http://osvdb.org/86051 http://secunia.com/advisories/50805 http://secunia.com/advisories/50888 http://w1.fi/gitweb/gitweb.cgi?p=hostap.git%3Ba=commitdiff%3Bh=586c446e0ff42ae00315b014924ec669023bd8de http://www.debian.org/security/2012/dsa-2557 http://www.freebsd.org/security/advisories/FreeBSD-SA-12:07.hostapd.asc http://www.mandriva.com/security/advisories?name=MDVSA-2012:168 http://www.openwall.com/lists/oss-security/2012/10/08/3 http://www.pre-cert.de/advisories/PRE-SA-2012&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
