  * Reset pid_child only if waitpid was successful.
    This is a regression fix for CVE-2017-2616. If su receives a signal like
    SIGTERM, it is not propagated to the child. (Closes: #862806)

+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,
+   OWL, LFS, Mandriva, Gentoo; are they already applied?)

+Subject: newgidmap: enforce setgroups=deny if self-mapping a group
+
+This is necessary to match the kernel-side policy of "self-mapping in a
+user namespace is fine, but you cannot drop groups" -- a policy that was
+created in order to stop user namespaces from allowing trivial privilege
+escalation by dropping supplementary groups that were "blacklisted" from
+certain paths.
+
+This is the simplest fix for the underlying issue, and effectively makes
+it so that unless a user has a valid mapping set in /etc/subgid (which
+only administrators can modify) -- and they are currently trying to use
+that mapping -- then /proc/$pid/setgroups will be set to deny. This
+workaround is only partial, because ideally it should be possible to set
+an "allow_setgroups" or "deny_setgroups" flag in /etc/subgid to allow
+administrators to further restrict newgidmap(1).
+
+We also don't write anything in the "allow" case because "allow" is the
+default, and users may have already written "deny" even if they
+technically are allowed to use setgroups. And we don't write anything if
+the setgroups policy is already "deny".

+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] su: properly clear child PID
+
+If su is compiled with PAM support, it is possible for any local user
+to send SIGKILL to other processes with root privileges. There are
+only two conditions. First, the user must be able to perform su with
+a successful login. This does NOT have to be the root user, even using
+su with the same id is enough, e.g. "su $(whoami)". Second, SIGKILL
+can only be sent to processes which were executed after the su process.
+It is not possible to send SIGKILL to processes which were already
+running. I consider this as a security vulnerability, because I was
+able to write a proof of concept which unlocked a screen saver of
+another user this way.

++.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

+Subject: [PATCH] Fix buffer overflow if NULL line is present in db.
+
+If ptr->line == NULL for an entry, the first cycle will exit,
+but the second one will happily write past entries buffer.
+We actually do not want to exit the first cycle prematurely
+on ptr->line == NULL.

+Small intro to the system for numbering the patches here...
+
+-The 00xx-... patches are forwarded to upstream's git repository
+
+-The 0xx_... series of patches are patches isolated from the latest
+ version of the shadow Debian package not using quilt in order to
+ separate upstream from Debian-specific stuff.
+
+ NO MORE PATCHES SHOULD BE ADDED IN THESE SERIES
+
+-The 1xx series are l10n patches to upstream 4.0.18.1. As upstream has
+ adopted Debian translations, it is very likely that these patches
+ will become useless when we will have synced with upstream
+
+-The 2xx series are patches for manual pages translations to upstream
+ 4.0.18.1.
+
+-The 3xx series are patches which have been temporarily applied to 
+ Debian's shadow while we *know* they have been applied upstream as well
+ These patches should NOT be kept when we will sync with upstream
+
+-The 4xx series are patches which have been applied to Debian's shadow
+ and have NOT been accepted and/or applied upstream. These patches MUST be kept
+ even after resynced with upstream
+
+-The 5xx series are patches which are applied to Debian's shadow
+ and will never be proposed upstream because they're too specific
+ This list SHOULD BE AS SHORT AS POSSIBLE
+
+In short, while we are working towards synchronisation with upstream,
+our goal is to make 0xx patches disappear by moving them either to 3xx
+series (things already implemented upstream) or to 4xx series
+(Debian-specific patches).
+
+
+Short HOWTO for quilt
+=====================
+
+The quilt system can be assimilated to a Pile Of Patches management system.
+Patches live in debian/patches, the working directory is "."
+
+The basic commands are (abbreviation accepted):
+quilt push (asks to apply the next patch in the pile)
+quilt pop  (removes the current patch and go up in the pile)
+quilt refresh (take the current changes in tree onto the patch)
+
+When a file is changed by a patch, quilt saves it somewhere under .pc on
+application. This is how it can refresh it afterward (comparing the version
+in .pc and the one you currently have in your working dir).
+
+There are three common pitfalls with quilt:
+ - doing "quilt pop" without doing "quilt refresh". The version of current
+     dir is replaced with the version of the .pc dir. Your changes are lost.
+   Quilt wont let you do so, but you can force it with '-f' if you're fool.
+ - editing a file with is not in the patch yet. Quilt didn't do any previous
+     backup.
+   Use "quilt add" to add files to patches.
+   Set $EDITOR and use "quilt edit" to edit a file, and add it onto the
+     patch if needed.
+ - If you update your working directory, patches may not revert cleanly.
+   It is thus recommended to use "quilt pop -a" before updating with
+   "svn up".
+   If you forget (and run into trouble), you may want to remove the whole
+   shadow-?.?.? directory. If you use the makefile which is in the upper
+   directory (trunk/), shadow-?.?.?/debian/patches is a link to
+   debian/patches, so this dirctory does not contain any valuable info.
+
+The documentation is quite well done, I think. "quilt -h" will list you the
+commands. "quilt <cmd> -h" will give you some hints about it. "man quilt" is
+a reference documentation. /usr/share/doc/quilt/quilt.pdf.gz is a complete
+manual, with tutorial.
