This week we examine another instance of a misbehaving certificate authority losing Chrome's trust. We cover a number of serious new vulnerabilities including an urgent update need for the just-released Gnu Privacy Guard; another supply chain attack against end users; a disastrous 10-year-old flaw in Linux's SUDO command; and, thanks to Google, some details of Apple's quietly redesigned sandboxing of iMessage in iOS 14. I'm going to share something that I think our listeners will find quite interesting about some recent architectural decisions for SpinRite, and then we'll conclude with a look at the inevitable improvement in NAT bypassing Slipstreaming.
