libselinux1-udeb 2.7-2 (armhf binary) in ubuntu bionic

 This package provides the shared libraries for Security-enhanced
 Linux that provides interfaces (e.g. library functions for the
 SELinux kernel APIs like getcon(), other support functions like
 getseuserbyname()) to SELinux-aware applications. Security-enhanced
 Linux is a patch of the Linux kernel and a number of utilities with
 enhanced security functionality designed to add mandatory access
 controls to Linux. The Security-enhanced Linux kernel contains new
 architectural components originally developed to improve the security
 of the Flask operating system. These architectural components provide
 general support for the enforcement of many kinds of mandatory access
 control policies, including those based on the concepts of Type
 Enforcement, Role-based Access Control, and Multi-level Security.

 libselinux1-udeb provides the libselinux shared library for use within
 the Debian installer. Do not install it on a normal system.
