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.

In the following code, a JarFile object is created from a downloaded file.
JarFile jf = new JarFile(f);
The JAR file that was potentially downloaded from an untrusted source is created without verifying the signature (if present). An alternate constructor that accepts a boolean verify parameter should be used instead.
