-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.

+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 ':'s and '\0's should be disallowed in group and usernames (other
+than '-' as the leading character).  Thus, the maintenance tools don't
+anymore.  closes: #79682, #166798, #171179
 
 Status wrt upstream: Debian specific. Not to be used upstream
 
-Details:
- Allows any non-empty user/grounames that don't contain ':', ',' or '\n'
- characters and don't start with '-', '+', or '~'. This patch is more
- restrictive than original Karl's version. closes: #264879
- Also closes: #377844
