Description

Bluetooth firmware or operating system software drivers in macOS versions before 10.13, High Sierra and iOS versions before 11.4, and Android versions before the 2018-06-05 patch may not sufficiently validate elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange, which may allow a remote attacker to obtain the encryption key used by the device.

Techniques & Countermeasures

  • CWE-325•Missing Cryptographic Step

    The product does not implement a required step in a cryptographic algorithm, resulting in weaker encryption than advertised by the algorithm.

  • CWE-347•Improper Verification of Cryptographic Signature

    The product does not verify, or incorrectly verifies, the cryptographic signature for data.
