VU#228519: Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to induce nonce and session key reuse

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.

VU#590639: NXP Semiconductors MQX RTOS contains multiple vulnerabilities

The NXP Semiconductors MQX RTOS prior to version 5.1 contains a buffer overflow in the DHCP client,which may lead to memory corruption allowing an attacker to execute arbitrary code,as well as an out of bounds read in the DNS client which may lead to a denial of service.

VU#240311: Multiple Bluetooth implementation vulnerabilities affect many devices

A collection of Bluetooth implementation vulnerabilities known as"BlueBorne"has been released. These vulnerabilities collectively affect Windows,iOS,and Linux-kernel-based operating systems including Android and Tizen,and may in worst case allow an unauthenticated attacker to perform commands on the device.

VU#166743: Das U-Boot AES-CBC encryption implementation contains multiple vulnerabilities

Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. For devices utilizing this environment encryption mode,U-Boot’s use of a zero initialization vector and improper handling of an error condition may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data.
