Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has linux-firmware packages installed that are affected by a vulnerability:

  • 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. (CVE-2018-5383)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
