nFPM is an alternative to fpm. The file permissions on the checked-in files were not maintained. Hence, when nfpm packaged the files (without extra config for enforcing it’s own permissions) files could go out with bad permissions (chmod 666 or 777). Anyone using nfpm for creating packages without checking/setting file permissions before packaging could result in bad permissions for files/folders.

Ubuntu Security Notice 6005-2 - USN-6005-1 fixed vulnerabilities in Sudo. This update provides the corresponding updates for Ubuntu 16.04 LTS. Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly escaped control characters in log messages and sudoreplay output. An attacker could possibly use these issues to inject terminal control characters that alter output when being viewed.
