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
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
