Severity: minor
Hi,
As seen on /etc/login.defs:
# If using MD5 in your PAM configuration, set this higher.
#
PASS_MAX_LEN 8
Which is consistent with the information in /etc/pam.d/login:
# (Add `md5' after the module name to enable MD5 passwords the same way
# that
# `MD5_CRYPT_ENAB' would do under login.defs).
#
password required pam_unix.so nullok obscure min=4 max=8 md5
But both files don't allow passwords to be larger than 8 characters, as
recommended by the comment in /etc/login.defs, and can't take full
advantage of MD5 possibilities. I'd recommend either remove the comment
line (easy, but "dirty" solution ;) or to extend maximun password length
to a value grater than 8 (maybe 12 or 16, don't know what C2 or B1
security requires).
Don't know for sure how the Debian installation process works, but as far
as I remember when selecting whether to use MD5 passwords or not, the
package is installed the usual way, so no special workarounds should be
required for this changes to work.
Greetings, and keep up the good work !

Changes:
shadow (1:4.0.3-36) unstable; urgency=low
.
* Debian specific programs fixes:
- Re-enable logging and displaying failures on login when login is
compiled with PAM and when FAILLOG_ENAB is set to yes. And create the
faillog file if it does not exist on postinst (as on Woody).
Closes: #192849
- do not localize login's syslog messages.
* Debian packaging fixes:
- Fix FTBFS with new dpkg 1.13 and use a correct dpkg-architecture
invocation. Closes: #314407
- Add a comment about potential sensitive information exposure
when LOG_UNKFAIL_ENAB is set in login.defs
Closes: #298773
- Remove limits.5 and limits.conf.5 man pages which do not
reflect the way we deal with limits in Debian
Closes: #288106, #244754
- debian/login.defs:
- Make SU_PATH and PATH consistent with the values used in /etc/profile
Closes: #286616
- Comment the UMASK setting which is more confusing than useful
as it only affects console logins. Better use pam_umask instead
Closes: #314539, #248150
- Add a comment about "appropriate" values for umask
Closes: #269583
- Correct the assertion about the variable defined by QMAIL_DIR
which is MAILDIR, not MAIL
Closes: #109279
- Move the PASS_MAX_LEN variable at the end of login.defs as this
is obsoleted when using PAM
Closes: #87301
- debian/passwd.config:
- Re-enable the password confirmation question at critical priority
Closes: #304350
- Do no prompt again for the login name when the two passwords don't
match while creating a new user
Closes: #245332
- debian/add-shell.sh, debian/remove-shell.sh, debian/shadowconfig.sh,
debian/passwd.config, debian/passwd.postinst:
- checked for bashisms, replaced "#!/bin/bash" with "#!/bin/sh",
Closes: #315767
- replaced "test XXX -a YYY" XSI:isms with "test XXX && test YYY",
for rationale see:
http://www.opengroup.org/onlinepubs/009695399/utilities/test.html
- replaced all unneeded "egrep"s with basic "grep"s
Closes: #256732
- debian/rules:
Remove the setuid bit on login
Closes: #298060
- debian/passwd.templates:
Templates rewrite to shorten them down a little and make them DTSG
compliant. Give more details about what the user's full name is used
for.
Closes: #287410
- Updated to Standards: 3.6.2 (checked)
* Debconf translation updates:
- Estonian added. Closes: #312471
- Basque updated. Closes: #314303

- Portuguese updated. Closes: #315375
- Simplified Chinese updated. Closes: #315567
- French updated
- Ukrainian updated. Closes: #315727

- Slovak updated. Closes: #315812
- Romanian updated. Closes: #315783
- Finnish updated. Closes: #315972
- Catalan updated. Closes: #316026
* Man pages translation updates:

which doesn't even mention sg
Closes: #261490
* Man pages correction for Debian specific issues:
- 402_usermod.8-system-users-range-286258:
Document the system user range from 0 to 999 in Debian
Closes: #286258
* Upstream bugs not fixed in upstream releases or CVS:
- 423_su_pass_args_without_concatenation
Thanks to Helmut Waitzmann.
Closes: #276419
* pass the argument to the shell or command without concatenation
before the call to exec.
* If no command is provided, the arguments after the username are for
the shell, no -c has to be appended.
- 008_su_ignore_SIGINT
* Also ignore SIGQUIT in su to avoid defeating the delay.
The gain in security is very minor.
Closes: #288827
- 424_pwck.8_quiet_option
pwck(8): document the -q option. Closes: #309408

regular /etc/group or /etc/passwd files and not in shadow/gshadow.
- 427_chage_expiry_0
Fix chage display in the case of null expiry fields (do not display
Never, but 01 Jan 1970)
Closes: #78961
* Upstream bugs already fixed in upstream releases or CVS:
- Corrected typos in chfn.1. Closes: #312428
- Corrected typos in gshadow.5. Closes: #312429
- Corrected typos in shadow.5. Closes: #312430
- Corrected typos in grpck.8. Closes: #312431

Added similar patch (357th) for newgrp. Both changes only affect
operation with CLOSE_SESSION set to yes (in /etc/login.defs).
Closes: #314727
* Translation updates:
- debian/patches/010_more-i18ned-messages
- More messages are translatable. We will deal with the translation
updates after syncing with upstream.
Closes: #266281
- debian/patches/114_eu:
- Basque translation update. Closes: #314423
- debian/patches/132_vi.dpatch:
