Package: vsftpd
Version: 3.0.3-8+b1
Severity: normal
The documentation in /usr/share/doc/vsftpd/examples/VIRTUAL_USERS/README.gz and
/usr/share/doc/vsftpd/examples/VIRTUAL_USERS/vsftpd.pam states that we should
have the following in /etc/pam.d/ftp:
auth required /lib/security/pam_userdb.so db=/etc/vsftpd_login
account required /lib/security/pam_userdb.so db=/etc/vsftpd_login
But when logging in to ftp this results in a login failure:
$ ftp localhost
Connected to localhost.
220 (vsFTPd 3.0.3)
Name (localhost:nick): username
331 Please specify the password.
Password:
530 Login incorrect.
Login failed.
ftp> exit
221 Goodbye.
Logging in twice produces the following status:
$ sudo service vsftpd status

Replacing the paths with names to modules in the ftp file as suggested at
https://bugzilla.redhat.com/show_bug.cgi?id=206216#c2 fixes the issue:
auth required pam_userdb.so db=/etc/vsftpd_login
account required pam_userdb.so db=/etc/vsftpd_login
I think the documentation should be updated at both places with the new ftp
file.

Changes:
vsftpd (3.0.5-1) unstable; urgency=medium
.
* Add debian/patches/0079-debian-bugfixes.patch to address multiple bugs:
- Return 502 Command not implemented instead of 550 for disabled
PASV/PORT commands (Closes: #1012476).
- Document the Debian-specific utf8_filesystem option in the
man page (Closes: #950577).
- Trim leading and trailing whitespace/tabs in vsftpd.conf parsing
to prevent startup failures due to extra spaces (Closes: #950584).
- Dynamically fall back to IPv4 listening if IPv6 is disabled in
the kernel, avoiding package installation and daemon startup
failures (Closes: #961712).
* Add debian/patches/0080-pam-exec-hang.patch to prevent hanging in
the SIGCHLD handler when using PAM modules that spawn subprocesses,
e.g. pam_exec (Closes: #952421, #827550).
* Add debian/patches/0081-pasv-address-ipv6.patch to fix pasv_address
being ignored when listen_ipv6 is enabled and clients connect
via IPv4 (Closes: #968888).
* Add debian/patches/0082-debian-bugfixes-tls-utf8.patch to fix:
- Cap TLS 1.3 session ticket lifetime at 7 days (604800s) instead
of INT_MAX to comply with RFC 8446, preventing connection drops on
both control and data channels (Closes: #929958, #958469).
- Allow UTF-8 characters (high bytes >= 128) in logs and fix 177
typo in printability check (Closes: #644920).
- Fix assignment typo in vsf_sysutil_realpath causing double slashes
when resolving paths under the root directory (Closes: #825271).
- Remove obsolete absolute paths to pam_userdb.so in virtual users
examples (Closes: #885402).
* Move adduser from Recommends to Depends to satisfy postinst script.
* Officially close historically resolved/satisfied bugs that were left
open in the Debian Bug Tracking System (Closes: #838678, #844297, #973766).
