VU#240311: Multiple Bluetooth implementation vulnerabilities affect many devices

A collection of Bluetooth implementation vulnerabilities known asBlueBornehas 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#306792: Bouncy Castle BKS-V1 keystore files vulnerable to trivial hash collisions

Bouncy Castle BKS version 1 keystore files use an HMAC that is only 16 bits long,which can allow an attacker to crack a BKS-V1 keystore file in seconds.

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#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.

VU#973527: Dnsmasq contains multiple vulnerabilities

Dnsmasq versions 2.77 and earlier contains multiple vulnerabilities.

VU#446847: Savitech USB audio drivers install a new root CA certificate

Savitech provides USB audio drivers for a number of specialized audio products.
Some versions of the Savitech driver package silently install a root CA certificate into the Windows trusted root certificate store.

VU#817544: Windows 8 and later fail to properly randomize every application...

Microsoft Windows 8 introduced a change in how system-wide mandatory ASLR is implemented.

This change requires system-wide bottom-up ASLR to be enabled for mandatory ASLR to receive entropy.

Tools that enable system-wide ASLR without also setting bottom-up ASLR will fail to properly randomize executables that do not opt in to ASLR.

VU#739007: IEEE P1735 implementations may have weak cryptographic protections

The P1735 IEEE standard describes methods for encrypting electronic-design intellectual property(IP),as well as the management of access rights for such IP.

The methods are flawed and,in the most egregious cases,enable attack vectors that allow recovery of the entire underlying plaintext IP.
Implementations of IEEE P1735 may be weak to cryptographic attacks that allow an attacker to obtain plaintext intellectual property without the key,among other impacts.

VU#421280: Microsoft Office Equation Editor stack buffer overflow

Microsoft Equation Editor contains a stack buffer overflow,which can allow a remote,unauthenticated attacker to execute arbitrary code on a vulnerable system.

VU#475445: Multiple SAML libraries may allow authentication bypass via incorrect XML...

Multiple SAML libraries may incorrectly utilize the results of XML DOM traversal and canonicalization APIs in such a way that an attacker may be able to manipulate the SAML data without invalidating the cryptographic signature,allowing the attack to potentially bypass authentication to SAML service providers.

VU#584653: CPU hardware vulnerable to side-channel attacks

CPU hardware implementations are vulnerable to cache side-channel attacks.

These vulnerabilities are referred to as Meltdown and Spectre.

VU#228519: Wi-Fi Protected Access (WPA) handshake traffic can be manipulated to...

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 orKRACKattacks.
