During the lifetime of an Ubuntu release, Canonical provides security maintenance. Basic Security Maintenance covers binary packages that reside in the 'main' and 'restricted' components of the Ubuntu archive, typically for a period of 5 years from LTS release.

For Ubuntu 16.04 LTS, where technically feasible, Canonical will provide extended security maintenance to all binary packages that reside in the Ubuntu Main Repository for 64-bit x86 AMD/Intel and s390 architectures. See the service description for additional details.
