TITLE

Bluetooth BR/EDR supported devices are vulnerable to key negotiation attacks

DESCRIPTION

The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing. Bluetooth BR/EDR The entropy negotiation of the encryption key used for encryption on the connection has a problem that is vulnerable to man-in-the-middle attacks by design. A third party Bluetooth BR/EDR The entropy of the encryption key used for communication 1 Force byte (Key Negotiation Of Bluetooth (KNOB) attack) Brute force attacks on subsequent communications (Brute force attack) May be able to decrypt and intercept the contents. Bluetooth Is Bluetooth Basic Rate / Enhanced Data Rate (Bluetooth BR/EDR) Includes core configuration 6 A short-range wireless technology based on different core specifications and used for low-power short-range communications. Bluetooth To establish encrypted communication for 2 Horn Bluetooth You need to establish a link key that the device will pair and use to generate the encryption key used for encryption at the link layer. The entropy of the encryption key is 1 From bytes 16 In bytes length Bluetooth Set between controllers. When an attacker interrupts the encryption key entropy setting request between controllers and each controller accepts a low entropy setting, encrypted communication with low entropy is forced, resulting in a brute force attack (Brute force attack) Because of this, communication between devices may be easily decrypted.Man-in-the-middle attacks (man-in-the-middle attack) There is a possibility of eavesdropping on encrypted communication by. An encryption issue vulnerability exists in Bluetooth BR/EDR 5.1 and earlier versions. The vulnerability stems from incorrect use of relevant cryptographic algorithms by network systems or products, resulting in improperly encrypted content, weak encryption, and storing sensitive information in plain text. The attack must be performed during negotiation or renegotiation of a paired device connection; existing sessions cannot be attacked. This advisory will be updated as additional information becomes available. There are no workarounds that address this vulnerability.

(CVE-2019-15215) It was discovered that a race condition existed in the Softmac USB Prism54 device driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15220) Benjamin Moody discovered that the XFS file system in the Linux kernel did not properly handle an error condition when out of disk quota. A local attacker could possibly use this to cause a denial of service. (CVE-2019-15538) It was discovered that the Hisilicon HNS3 ethernet device driver in the Linux kernel contained an out of bounds access vulnerability. A local attacker could use this to possibly cause a denial of service (system crash). (CVE-2019-15925) It was discovered that the Atheros mobile chipset driver in the Linux kernel did not properly validate data in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2019-15926) Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. A physically proximate attacker could use this to expose sensitive information. (CVE-2019-9506) It was discovered that ZR364XX Camera USB device driver for the Linux kernel did not properly initialize memory. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15217) It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel made improper assumptions about the device characteristics. A physically proximate attacker could use this cause a denial of service (system crash). (CVE-2019-15218) It was discovered that the Line 6 POD USB device driver in the Linux kernel did not properly validate data size information from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15221) It was discovered that the Line 6 USB driver for the Linux kernel contained a race condition when the device was disconnected. A physically proximate attacker could use this to cause a denial of service (system crash).

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
