CVE-2020-6616: Medium severity macos catalina vulnerability

Published Mar 24, 2020
·
Updated

Bluetooth. An issue existed with the use of a PRNG with low entropy. This issue was addressed with improved state management.

Other sources

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).
