Security warning from pam_securetty
Is the bug #243698 in libpam0g really resolved in version 0.76-20? I
still get the security warnings in my logfiles. What is referred to in
the changelog.Debian for the null password check: passwd, shadow etc?
How are these related to the /etc/pam.d/* files. Eg. the
/etc/pam.d/common-password has the following entry enabled:
password required pam_unix.so nullok obscure min=4 max=8 md5
An alternate solution is in the same file. Is this solution to prefer?
# password required pam_cracklib.so retry=3 minlen=6 difok=3
# password required pam_unix.so use_authtok nullok md5
If possible, please explain or if possible give a HOWTO- or an
FAQ-pointer that describes the current pam behaviour.
changelog.Debian entry below:
pam (0.76-20) unstable; urgency=medium
* Update to patch 55 to only check securetty when we are sure the
password is null, Closes: #243698
* Medium urgency because the version now in testing has confusing and
verbose log messages.
* Include pam_getenv script which hopefully will be used by some
people somewhere for some purpose
