/* This module allows programs which are installed with setuid or setgid bit
(and which therefore initially run with an effective user id or group id
different from the one of the current user) to drop their uid or gid
privilege, either permanently or temporarily.
It is absolutely necessary to minimize the amount of code that is running
with escalated privileges (e.g. with effective uid = root). The reason is
that any bug or exploit in a part of a program that is running with
escalated privileges is a security vulnerability that - upon discovery -
puts the users in danger and requires immediate fixing. Then consider that
there's a bug every 10 or 20 lines of code on average...
For programs that temporarily drop privileges but have the ability to
restore them later, there are additionally the dangers that
- Any bug in the non-privileged part of the program may be used to
create invalid data structures that will trigger security
vulnerabilities in the privileged part of the program.
- Code execution exploits in the non-privileged part of the program may
be used to invoke the function that restores high privileges and then
execute additional arbitrary code.
1) The usual, and reasonably safe, way to minimize the amount of code
running with privileges is to create a separate executable, with setuid
or setgid bit, that contains only code for the tasks that require
privileges (and,of course, strict checking of the arguments, so that the
program cannot be abused). The main program is installed without setuid
or setgid bit.
2) A less safe way is to do some privileged tasks at the beginning of the
program's run, and drop privileges permanently as soon as possible.
Note: There may still be security issues if the privileged task puts
sensitive data into the process memory or opens communication channels
to restricted facilities.
3) The most unsafe way is to drop privileges temporarily for most of the
main program but to re-enable them for the duration of privileged tasks.
As explained above, this approach has uncontrollable dangers for
security.
This approach is normally not usable in multithreaded programs, because
you cannot know what kind of system calls the other threads could be
doing during the time the privileges are enabled.
With approach 1, you don't need gnulib modules.
With approach 2, you need the gnulib module 'idpriv-drop'.
With approach 3, you need the gnulib module 'idpriv-droptemp'. But really,
you should better stay away from this approach.
