* pam_motd: Fix segmentation fault when no motd_dir specified (#76)Robert Fairley2018-11-21
| | | | | | | | | | | | This fixes a regression introduced by #69, where motd_path was set to NULL and passed into strdup() if the motd_dir argument was not specified in the configuration file. This caused a segmentation fault. * modules/pam_motd/pam_motd.c: fix checks for NULL in arguments * xtests/Makefile.am: add test scripts and config file * xtests/tst-pam_motd.sh: add running tst-pam_motd4.sh * xtests/tst-pam_motd4.pamd: create * xtests/tst-pam_motd4.sh: create
* pam_motd: Support multiple motd paths specified, with filename overrides (#69)Robert Fairley2018-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds specifying multiple paths to motd files and motd.d directories to be displayed. A colon-separated list of paths is specified as arguments motd and motd_dir to the pam_motd module. This gives packages several options to install motd files to. By default, the paths are, with highest priority first: /etc/motd /run/motd /usr/lib/motd /etc/motd.d/ /run/motd.d/ /usr/lib/motd.d/ Which is equivalent to the following arguments: motd=/etc/motd:/run/motd:/usr/lib/motd motd_dir=/etc/motd.d:/run/motd.d:/usr/lib/motd.d Files with the same filename in a lower-priority directory, as specified by the order in the colon-separated list, are overridden, meaning PAM will not display them. This allows a package to contain motd files under /usr/lib instead of the host configuration in /etc. A service may also write a dynamically generated motd in /run/motd.d/ and have PAM display it without needing a symlink from /etc/motd.d/ installed. Closes #68 * modules/pam_motd/pam_motd.8.xml: update documentation * modules/pam_motd/pam_motd.c: add specifying multiple motd paths * xtests/.gitignore: add generated test script * xtests/Makefile.am: add test source, scripts and config files * xtests/tst-pam_motd.c: create * xtests/tst-pam_motd.sh: create * xtests/tst-pam_motd1.pamd: create * xtests/tst-pam_motd1.sh: create * xtests/tst-pam_motd2.pamd: create * xtests/tst-pam_motd2.sh: create * xtests/tst-pam_motd3.pamd: create * xtests/tst-pam_motd3.sh: create
* pam_unix: Use bcrypt b-variant for computing new hashes.Björn Esser2018-11-16
| | | | | | | | | | | | | | | Bcrypt hashes used the "$2a$" prefix since 1997. However, in 2011 an implementation bug was discovered in bcrypt affecting the handling of characters in passphrases with the 8th bit set. Besides fixing the bug, OpenBSD 5.5 introduced the "$2b$" prefix for a behavior that exactly matches crypt_blowfish's "$2y$", and the crypt_blowfish implementation supports it as well since v1.1. That said new computed bcrypt hashes should use the "$2b$" prefix. * modules/pam_unix/passverify.c: Use bcrypt b-variant.

* pam_stress: do not mark messages for translationDmitry V. Levin2018-06-19

* pam_unix: remove obsolete _UNIX_AUTHTOK, _UNIX_OLD_AUTHTOK, and ↵Dmitry V. Levin2018-05-31

* pam_motd: add support for a motd.d directory (#48)Allison Karlitskaya2018-05-16
| | | | | | | | | | | | | | | Add a new feature to pam_motd to allow packages to install their own message files in a "motd.d" directory, to be displayed after the primary motd. Add an option motd_d= to specify the location of this directory. Modify the defaults, in the case where no options are given, to display both /etc/motd and /etc/motd.d. Fixes #47 * modules/pam_motd/pam_motd.c: add support for motd.d * modules/pam_motd/pam_motd.8.xml: update the manpage

| | | | | * modules/pam_umask/pam_umask.8.xml: Document the real order of loading umask.
* pam_tally2 --reset: avoid creating a missing tallylog fileDmitry V. Levin2017-11-10
| | | | | | | | | | | | | | | | There is no need for pam_tally2 in --reset=0 mode to create a missing tallylog file because its absence has the same meaning as its existence with the appropriate entry reset. This was not a big deal until useradd(8) from shadow suite release 4.5 started to invoke /sbin/pam_tally2 --reset routinely regardless of PAM configuration. The positive effect of this change is noticeable when using tools like cpio(1) that cannot archive huge sparse files efficiently. * modules/pam_tally2/pam_tally2.c [MAIN] (main) <cline_user>: Stat cline_filename when cline_reset == 0, exit early if the file is missing.

* Release version 1.2.1Thorsten Kukuk2015-06-22
| | | | | | | | | | | | | | | | | | | | | | | | Security fix: CVE-2015-3238 If the process executing pam_sm_authenticate or pam_sm_chauthtok method of pam_unix is not privileged enough to check the password, e.g. if selinux is enabled, the _unix_run_helper_binary function is called. When a long enough password is supplied (16 pages or more, i.e. 65536+ bytes on a system with 4K pages), this helper function hangs indefinitely, blocked in the write(2) call while writing to a blocking pipe that has a limited capacity. With this fix, the verifiable password length will be limited to PAM_MAX_RESP_SIZE bytes (i.e. 512 bytes) for pam_exec and pam_unix. * NEWS: Update * configure.ac: Bump version * modules/pam_exec/pam_exec.8.xml: document limitation of password length * modules/pam_exec/pam_exec.c: limit password length to PAM_MAX_RESP_SIZE * modules/pam_unix/pam_unix.8.xml: document limitation of password length * modules/pam_unix/pam_unix_passwd.c: limit password length * modules/pam_unix/passverify.c: Likewise * modules/pam_unix/passverify.h: Likewise * modules/pam_unix/support.c: Likewise
