Add Salsa-CI config

shadow (1:4.2-3+deb8u6) jessie-security; urgency=high
.
  * Non-maintainer upload by the ELTS Security Team.
  * CVE-2023-4641: When asking for a new password, shadow-utils asks the
    password twice. If the password fails on the second attempt,
    shadow-utils fails in cleaning the buffer used to store the first
    entry. This may allow an attacker with enough access to retrieve the
    password from the memory. (Closes: #1051062)
  * CVE-2023-29383: It is possible to inject control characters into
    fields provided to the SUID program chfn (change finger). Although it
    is not possible to exploit this directly (e.g., adding a new user
    fails because \n is in the block list), it is possible to misrepresent
    the /etc/passwd file when viewed. (Closes: #1034482)

+============
 
-## 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.

+** 03/17/96
+** hacked a bit more, removed unused code, cleaned up for gcc -Wall.
+** --marekm
+**
+** 02/26/96
+** modified to call shadow utils (useradd,chage,passwd) on shadowed 
+** systems - Cristian Gafton, gafton@sorosis.ro
+**
+** 6/27/95
+** shadow-adduser 1.4:
+**
+** now it copies the /etc/skel dir into the person's dir, 
+** makes the mail folders, changed some defaults and made a 'make 
+** install' just for the hell of it.
+**
+** Greg Gallagher
+** CIN.Net
+**
+** 1/28/95
+** shadow-adduser 1.3:
+** 
+** Basically a bug-fix on my additions in 1.2.  Thanx to Terry Stewart 
+** (stew@texas.net) for pointing out one of the many idiotic bugs I introduced.
+** It was such a stupid bug that I would have never seen it myself.
+**

+*****
+** 01/27/95
+** 
+** 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)
+**                       for us all to use (and Email it to me???)
+**
+**                               Brandon

+** With a nice little interface and a will to do all the work for you.
+**
+** Craig Hagan
+** hagan@opine.cs.umass.edu

+** chris@slinky.cs.umass.edu

+*****

+** FURTHER modifications to enable shadow passwd support (kludged, but
+** no more so than the original)  by Dan Crowson - dcrowson@mo.net
+**
+** Search on DAN for all changes...
+**
+*****
+**
+** cc -O -o adduser adduser.c
+** Use gcc if you have it... (political reasons beyond my control) (chris)
+**
+** I've gotten this program to work with success under Linux (without
+** shadow) and SunOS 4.1.3. I would assume it should work pretty well
+** on any system that uses no shadow. (chris)
+**
+** If you have no crypt() then try
+** cc -DNO_CRYPT -O -o adduser adduser.c xfdes.c
+** I'm not sure how login operates with no crypt()... I guess
+** the same way we're doing it here.

 Description: system login tools
- This package provides some required infrastructure for logins and for
- changing effective user or group IDs, including:
-  * login, the program that invokes a user shell on a virtual terminal;
-  * nologin, a dummy shell for disabled user accounts;
+ These tools are required to be able to login and use your system. The
+ login program invokes your user shell and enables command execution. The
+ newgrp program is used to change your effective group ID (useful for
+ workgroup type situations). The su program allows changing your effective
+ user ID (useful being able to execute commands as another user).

-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.

+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.

+Do not reset the pid_child to 0 if the child process is still

+
+This is a regression fix for CVE-2017-2616. If su receives a

+Subject: [PATCH] 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".

 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.

-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.

+Description: subordinateio: Fix subordinate_parse to have an internal static buffer
+ subordinate_parse is supposed to return a static structure that
+ represents one line in /etc/subuid or /etc/subgid.  I goofed and
+ failed to make the variable rangebuf that holds the username of
+ in the returned structure static.
+ .
+ Add this missing static specification.

+Date: Fri, 21 Jun 2013 11:47:36 -0500
+Subject: [PATCH 1/1] userns: add argument sanity checking
+
+In find_new_sub_{u,g}ids, check for min, count and max values.
+
+In idmapping.c:get_map_ranges(), make sure that the value passed
+in for ranges did not overflow.  Couldn't happen with the current
+code, but this is a sanity check for any future potential mis-uses.
