Vinícius dos Santos Oliveira 05e2adf509 Validate fds created by the user
write_mapping() will do the following:

openat(proc_dir_fd, map_file, O_WRONLY);

An attacker could create a directory containing a symlink named
"uid_map" pointing to any file owned by root, and thus allow him to
overwrite any root-owned file.

shadow-utils

Introduction

The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
