ESP32 Backdoor Drama and SAML Auth Bypasses

Discussion this week starts with the ESP32 "backdoor" drama that circled the media, with some XML-based vulnerabilities in the mix. Finally, we cap off with a post on reviving modprobe_path for Linux exploitation, and some discussion around an attack chain against China that was attributed to the NSA.
