Samanta Navarro 4ef4477535 get_pid.c: Use tighter validation checks
Neither a pid_t below 1 nor a negative fd could be valid in this context.

Proof of Concept:

$ newuidmap -1 1 1 1
newuidmap: Could not open proc directory for target 4294967295

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.
