+## 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.

-** shadow-adduser 1.2:
-** I took the C source from adduser-shadow (credits are below) and made
-** it a little more worthwhile.  Many small changes... Here's
-** the ones I can remember:
-** 
-** Removed support for non-shadowed systems (if you don't have shadow,
-**     use the original adduser, don't get this shadow version!)
-** Added support for the correct /etc/shadow fields (Min days before
-**     password change, max days before password change, Warning days,
-**     and how many days from expiry date does the account go invalid)
-**     The previous version just left all of those fields blank.
-**     There is still one field left (expiry date for the account, period)
-**     which I have left blank because I do not use it and didn't want to
-**     spend any more time on this.  I'm sure someone will put it in and
-**     tack another plethora of credits on here. :)
-** Added in the password date field, which should always reflect the last
-**     date the password was changed, for expiry purposes.  "passwd" always
-**     updates this field, so the adduser program should set it up right
-**     initially (or a user could keep thier initial password forever ;)
-**     The number is in days since Jan 1st, 1970.
-**
-**                       Have fun with it, and someone please make
-**                       a real version(this is still just a hack)

+Read this file first for a brief overview of the new versions of login
+and passwd.
+
+
+---Shadow passwords
+
+The command `shadowconfig on' will turn on shadow password support.
+`shadowconfig off' will turn it back off.  If you turn on shadow
+password support, you'll gain the ability to set password ages and
+expirations with chage(1).
+
+NOTE: If you use the nscd package, you may have problems with a
+slight delay in updating the password information. You may notice
+this during upgrades of certain packages that try to add a system
+user and then access the users information immediately afterwards.
+To avoid this, it is suggested that you stop the nscd daemon before
+upgrades, then restart it again.
+
+---General configuration
+
+Most of the configuration for the shadow utilities is in
+/etc/login.defs.  See login.defs(5).  The defaults are quite
+reasonable.
+
+Also see the /etc/pam.d/* files for each program to configure the PAM
+support. PAM documentation is available in several formats in the
+libpam-doc package.
+
+
+---MD5 Encryption
+
+This is enabled now using the /etc/pam.d/* files. Examples are given.
+
+
+---Adding users and groups
+
+Though you may add users and groups with the SysV type commands,
+useradd and groupadd, I recommend you add them with Debian adduser
+version 3+.  adduser gives you more configuration and conforms to the
+Debian UID and GID allocation.
+
+Editing user and group parameters can be done with usermod and
+groupmod.  Removing users and groups can be done with userdel and
+groupdel.
+
+
+--- Group administration
+
+Local group allocation is much easier.  With gpasswd(1) you can
+designate users to administer groups.  They can then securely add or
+remove users from the group.
+
+
+--- What to read next?
+
+Read the manpages, the other files in this directory, and the Shadow
+Password HOWTO (included in the doc-linux package).  A large portion
+of these files deals with getting shadow installed.  You can, of
+course, ignore those parts.
+
+Also, the libpam-doc package will go a long way to allowing you to take
+full advantage of the PAM authentication scheme.

+Things that should be done:
+ * Verify the files left in debian/tmp
+   + e.g. /etc/default/adduser should be installed
+ * Check the build system: rebuilding the package twoce in the same tree
+   doubles the size of the diff.gz file
+
+Other points (not related to the release of a syncronized shadow):
+ * compare the source with the usages and man pages
+   + probably add a sentence to chsh/chfn's manpages about authentication
+     required for ordinary users
+ * do something (a tool) for the variables in login.defs
+   In Debian, some tools are not compiled with the PAM support, so upstream
+   getdef.c won't be OK.
+   It should be nice to see in each man page the set of variables used.
+   The Debian package can now compile (export DEB_BUILD_OPTIONS='nostrip debug')
+   with the debugging informations. This may be used to extract the set of
+   variables used in Debian/for each tools.
+ * verify all the patches around (I've found patches for at least RedHat,

+Subject: [PATCH] gpasswd(1): Fix password leak
+
+How to trigger this password leak?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When gpasswd(1) asks for the new password, it asks twice (as is usual
+for confirming the new password).  Each of those 2 password prompts
+uses agetpass() to get the password.  If the second agetpass() fails,
+the first password, which has been copied into the 'static' buffer
+'pass' via STRFCPY(), wasn't being zeroed.
+
+agetpass() is defined in <./libmisc/agetpass.c> (around line 91), and
+can fail for any of the following reasons:
+
+-  malloc(3) or readpassphrase(3) failure.
+
+   These are going to be difficult to trigger.  Maybe getting the system
+   to the limits of memory utilization at that exact point, so that the
+   next malloc(3) gets ENOMEM, and possibly even the OOM is triggered.
+   About readpassphrase(3), ENFILE and EINTR seem the only plausible
+   ones, and EINTR probably requires privilege or being the same user;
+   but I wouldn't discard ENFILE so easily, if a process starts opening
+   files.
+
+-  The password is longer than PASS_MAX.
+
+   The is plausible with physical access.  However, at that point, a
+   keylogger will be a much simpler attack.
+
+And, the attacker must be able to know when the second password is being
+introduced, which is not going to be easy.
+
+How to read the password after the leak?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Provoking the leak yourself at the right point by entering a very long
+password is easy, and inspecting the process stack at that point should
+be doable.  Try to find some consistent patterns.
+
+Then, search for those patterns in free memory, right after the victim
+leaks their password.
+
+Once you get the leak, a program should read all the free memory
+searching for patterns that gpasswd(1) leaves nearby the leaked
+password.

+
+How to fix it?
+~~~~~~~~~~~~~~
+
+memzero(), which internally calls explicit_bzero(3), or whatever
+alternative the system provides with a slightly different name, will
+make sure that the buffer is zeroed in memory, and optimizations are not
+allowed to impede this zeroing.
+
+This is not really 100% effective, since compilers may place copies of
+the string somewhere hidden in the stack.  Those copies won't get zeroed
+by explicit_bzero(3).  However, that's arguably a compiler bug, since
+compilers should make everything possible to avoid optimizing strings
+that are later passed to explicit_bzero(3).  But we all know that
+sometimes it's impossible to have perfect knowledge in the compiler, so
+this is plausible.  Nevertheless, there's nothing we can do against such
+issues, except minimizing the time such passwords are stored in plain
+text.
+
+Security concerns
+~~~~~~~~~~~~~~~~~
+
+We believe this isn't easy to exploit.  Nevertheless, and since the fix
+is trivial, this fix should probably be applied soon, and backported to
+all supported distributions, to prevent someone else having more
+imagination than us to find a way.
+
+Affected versions
+~~~~~~~~~~~~~~~~~
+
+All.  Bug introduced in shadow 19990709.  That's the second commit in
+the git history.
+
+Fixes: 45c6603cc86c ("[svn-upgrade] Integrating new upstream version, shadow (19990709)")

+Subject: [PATCH] Overhaul valid_field()
+
+e5905c4b ("Added control character check") introduced checking for
+control characters but had the logic inverted, so it rejects all
+characters that are not control ones.
+
+Cast the character to `unsigned char` before passing to the character
+checking functions to avoid UB.
+
+Use strpbrk(3) for the illegal character test and return early.

+shadowconfig \- active ou désactive les mots de passe cachés
+.SH SYNOPSIS
+\fBshadowconfig\fP \fIon\fP | \fIoff\fP
+.SH DESCRIPTION
+.PP
+\fBshadowconfig on\fP active les mots de passe cachés («\ shadow passwords\ »)\ ; \fBshadowconfig off\fP les désactive. \fBShadowconfig\fP affiche un message
+d'erreur et quitte avec une valeur de retour non nulle s'il rencontre
+quelque chose d'inattendu. Dans ce cas, vous devrez corriger l'erreur avant
+de recommencer.
+
+Activer les mots de passe cachés lorsqu'ils sont déjà activés, ou les
+désactiver lorsqu'ils ne sont pas actifs est sans effet.
+
+Lisez \fI/usr/share/doc/passwd/README.Debian\fP pour une brève introduction aux
+mots de passe cachés et à leurs fonctionnalités.
+
+Notez que désactiver puis réactiver les mots de passe cachés aura pour
+conséquence la perte des informations d'âge sur les mots de passe.

+ Allows any non-empty user/grounames that don't contain ':', ',' or '\n'

+ Comments from Karl Ramm (shadow 1:4.0.3-9, 20 Aug 2003 02:06:50 -0400):
+ 
+ I can't come up with a good justification as to why characters other

+ than '-' as the leading character).  Thus, the maintenance tools don't
+ anymore.  closes: #79682, #166798, #171179

+-The 00xx-... patches are forwarded to upstream's git repository

+-The 4xx series are patches which have been applied to Debian's shadow

+Subject: [PATCH] src/groupmod.c: delete gr_free_members(&grp) to avoid double
+ free
+
+Groupmod -U may cause crashes because of double free. If without -a, the first free of (*ogrp).gr_mem is in gr_free_members(&grp), and then in gr_update without -n or gr_remove with -n.
+Considering the minimal impact of modifications on existing code, delete gr_free_members(&grp) to avoid double free.Although this may seem reckless, the second free in two different positions will definitely be triggered, and the following two test cases can be used to illustrate the situation :
+
+[root@localhost src]# ./useradd u1
+[root@localhost src]# ./useradd u2
+[root@localhost src]# ./useradd u3
+[root@localhost src]# ./groupadd -U u1,u2,u3 g1
+[root@localhost src]# ./groupmod -n g2 -U u1,u2 g1
+Segmentation fault
+
+This case would free (*ogrp).gr_mem in gr_free_members(&grp) due to assignment statements grp = *ogrp, then in if (nflg && (gr_remove (group_name) == 0)), which finally calls gr_free_members(grent) to free (*ogrp).gr_mem again.
+
+[root@localhost src]# ./useradd u1
+[root@localhost src]# ./useradd u2
+[root@localhost src]# ./useradd u3
+[root@localhost src]# ./groupadd -U u1,u2,u3 g1
+[root@localhost src]# ./groupmod -U u1,u2 g1
+Segmentation fault
+
+The other case would free (*ogrp).gr_mem in gr_free_members(&grp) too, then in if (gr_update (&grp) == 0), which finally calls gr_free_members(grent) too to free (*ogrp).gr_mem again.
+
+So the first free is unnecessary, maybe we can drop it.
+
+Fixes: 342c934a3590 ("add -U option to groupadd and groupmod")
