CVE-2017-13077 – wpa_supplicant: Reinstallation of the pairwise key in the 4-way handshake
https://notcve.org/view.php?id=CVE-2017-13077
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 •
CVE-2017-14491 – Dnsmasq < 2.78 - 2-byte Heap Overflow
https://notcve.org/view.php?id=CVE-2017-14491
Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response. Un desbordamiento de búfer basado en memoria dinámica (heap) en dnsmasq en versiones anteriores a la 2.78 permite a los atacantes provocar una denegación de servicio (cierre inesperado) o ejecutar código arbitrario utilizando una respuesta DNS manipulada. A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. Dnsmasq versions prior to 2.78 suffer from a 2-byte heap-based overflow vulnerability. • https://www.exploit-db.com/exploits/42941 https://github.com/skyformat99/dnsmasq-2.4.1-fix-CVE-2017-14491 http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00006.html http://nvidia.custhelp.com/app/answers/detail/a_id/4560 http://nvidia.custhelp.com/a • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-1000366
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. Glibc contiene una vulnerabilidad que permite que los valores LD_LIBRARY_PATH especialmente creados para manipular la región heap/stack de la memoria, generando entonces un alias, lo que podría conllevar a la ejecución del código arbitrario. Tenga en cuenta que se han realizado cambios de refuerzo adicionales en glibc para evitar la manipulación del stack y heap de la memoria de almacenamiento dinámico, pero estos problemas no se pueden explotar directamente, por lo que no se les ha otorgado un CVE. • https://www.exploit-db.com/exploits/42276 https://www.exploit-db.com/exploits/42274 https://www.exploit-db.com/exploits/42275 http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 http://www.debian.org/security/2017/dsa-3887 http://www.securityfocus.com/bid/99127 http://www.securitytracker.com/id/1038712 https://access.redhat.com/errata/RHSA-2017:1479 https://access.redhat.com/errata/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-7995
https://notcve.org/view.php?id=CVE-2017-7995
Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL. Xen PV guest anterior a Xen 4.3 chequea los permisos de acceso a los rangos MMIO sólo después de acceder a ellos, lo que permite leer en un dispositivo de memoria PCI, dando lugar a la divulgación de información.
