+## 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)
-**                       for us all to use (and Email it to me???)

-** I've gotten this program to work with success under Linux (without

-** on any system that uses no shadow. (chris)

+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] 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] 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

+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.
