CVE-2020-6616
https://notcve.org/view.php?id=CVE-2020-6616
Some Broadcom chips mishandle Bluetooth random-number generation because a low-entropy Pseudo Random Number Generator (PRNG) is used in situations where a Hardware Random Number Generator (HRNG) should have been used to prevent spoofing. This affects, for example, Samsung Galaxy S8, S8+, and Note8 devices with the BCM4361 chipset. The Samsung ID is SVE-2020-16882 (May 2020). Algunos chips Broadcom manejan inapropiadamente la generación de números aleatorios de Bluetooth porque es usado un Pseudo Random Number Generator (PRNG) de baja entropía en situaciones en las que debería haberse utilizado un Hardware Random Number Generator (HRNG) para impedir la suplantación de identidad. Esto afecta, por ejemplo, a los dispositivos Samsung Galaxy S8, S8+ y Note8 con el chipset BCM4361. • http://bluetooth.lol http://seclists.org/fulldisclosure/2020/May/49 https://github.com/seemoo-lab/internalblue/blob/master/doc/rng.md https://media.ccc.de/v/DiVOC-6-finding_eastereggs_in_broadcom_s_bluetooth_random_number_generator https://security.samsungmobile.com/securityUpdate.smsb https://support.apple.com/HT211168 https://support.apple.com/kb/HT211100 https://support.apple.com/kb/HT211168 https://twitter.com/naehrdine/status/1255980443368919045 https://twitter.com/naehrdine/status/ •
