2019-12-12 CVE-2019-19726 Improper Privilege Management vulnerability in Openbsd

2019-12-11 CVE-2019-14899 Man-in-the-Middle vulnerability in multiple products
A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream.
