UR+ (Universal Robots+) is a platform of hardware and software component sellers, for Universal Robots robots. When installing any of these components in the robots (e.g. in the UR10), no integrity checks are performed. Moreover, the SDK for making such components can be easily obtained from Universal Robots. An attacker could exploit this flaw by crafting a custom component with the SDK, performing Person-In-The-Middle attacks (PITM) and shipping the maliciously-crafted component on demand.
The pc-kernel snap build process hardcoded the --allow-insecure-repositories and --allow-unauthenticated apt options when creating the build chroot environment. This could allow an attacker who is able to perform a MITM attack between the build environment and the Ubuntu archive to install a malicious package within the build chroot. This issue affects pc-kernel versions prior to and including 2019-07-16
