In version 6.5 Microchip MiWi software and all previous versions including legacy products, the stack is validating only two out of four Message Integrity Check (MIC) bytes. En la versión 6.5 del software Microchip MiWi y en todas las versiones anteriores, incluidos los productos heredados, la pila sólo valida dos de los cuatro bytes de comprobación de integridad de mensajes (MIC) • https://ww1.microchip.com/downloads/en/DeviceDoc/asf-release-notes-3.50.0.100-readme.pdf https://ww1.microchip.com/downloads/en/DeviceDoc/asf-release-notes-3.51.0.101-readme.pdf https://www.microchip.com/en-us/development-tools-tools-and-software/libraries-code-examples-and-more/advanced-software-framework-for-sam-devices#Downloads https://www.microchip.com/en-us/products/wireless-connectivity/software-vulnerability-response/miwi-software-vulnerability https://www.microchip.com/en-us/products/wireless-connectivit • CWE-670: Always-Incorrect Control Flow Implementation •

In version 6.5 of Microchip MiWi software and all previous versions including legacy products, there is a possibility of frame counters being validated/updated prior to the message authentication. With this vulnerability in place, an attacker may increment the incoming frame counter values by injecting messages with a sufficiently large frame counter value and invalid payload. This results in denial of service/valid packets in the network. There is also a possibility of a replay attack in the stack. En la versión 6.5 del software Microchip MiWi y en todas las versiones anteriores, incluidos los productos heredados, existe la posibilidad de que los contadores de tramas se validen/actualicen antes de la autenticación del mensaje. • https://ww1.microchip.com/downloads/en/DeviceDoc/asf-release-notes-3.50.0.100-readme.pdf https://www.microchip.com/en-us/development-tools-tools-and-software/libraries-code-examples-and-more/advanced-software-framework-for-sam-devices#Downloads https://www.microchip.com/en-us/products/wireless-connectivity/software-vulnerability-response/miwi-software-vulnerability https://www.microchip.com/en-us/products/wireless-connectivity/sub-ghz/miwi-protocol https://www.microchip.com/product-change-notifications/# • CWE-670: Always-Incorrect Control Flow Implementation •

Bleichenbacher's attack on PKCS #1 v1.5 padding for RSA in Microchip Libraries for Applications 2018-11-26 All up to 2018-11-26. The vulnerability can allow one to use Bleichenbacher's oracle attack to decrypt an encrypted ciphertext by making successive queries to the server using the vulnerable library, resulting in remote information disclosure. Un ataque de Bleichenbacher en el relleno PKCS#1 versión v1.5 para RSA en las Bibliotecas de Microchip para Aplicaciones en todas las versiones del 26-11-2018 hasta el 26-11-2018. La vulnerabilidad puede permitir a uno usar el ataque de oráculo de Bleichenbacher para descifrar un texto encriptado cifrado al hacer consultas sucesivas al servidor usando la biblioteca vulnerable, resultando en una divulgación de información remota • http://archiv.infsec.ethz.ch/education/fs08/secsem/bleichenbacher98.pdf http://microchip.com https://bi-zone.medium.com/silence-will-fall-or-how-it-can-take-2-years-to-get-your-vuln-registered-e6134846f5bb https://www.microchip.com/mplab/microchip-libraries-for-applications • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 headers does not validate whether the IPv6 payload length field is equal to the actual size of the payload, which leads to an Out-of-Bounds read during the ICMPv6 checksum calculation, resulting in either Denial-of-Service or Information Disclosure. This affects pico_ipv6_extension_headers and pico_checksum_adder (in pico_ipv6.c and pico_frame.c). Se detectó un problema en picoTCP versión 1.7.0. El código para procesar los encabezados de IPv6 no comprueba si el campo de longitud de la carga útil de IPv6 es igual al tamaño real de la carga útil, lo que conlleva a una Lectura Fuera de Límites durante el cálculo de la suma de comprobación ICMPv6, resultando en una Denegación de Servicio o Divulgación de información. • https://us-cert.cisa.gov/ics/advisories/icsa-20-343-01 https://www.kb.cert.org/vuls/id/815128 • CWE-125: Out-of-bounds Read •
