* pam_unix: workaround the problem caused by libnss_systemdDmitry V. Levin2021-08-191-2/+1
| | | | | | | | | | | | | | | | | | | The getspnam(3) manual page says that errno shall be set to EACCES when the caller does not have permission to access the shadow password file. Unfortunately, this contract is broken when libnss_systemd is used in the nss stack. Workaround this problem by falling back to the helper invocation when pam_modutil_getspnam returns NULL regardless of errno. As pam_unix already behaves this way when selinux is enabled, it should be OK for the case when selinux is not enabled, too. * modules/pam_unix/passverify.c (get_account_info): When pam_modutil_getspnam returns NULL, unconditionally fall back to the helper invocation.

| | | | | | | | | | | | | | | | | | | | Failing to check the descriptor value meant that there was a bug in the attempt to close the controlling tty. Moreover, this would lead to a file descriptor leak as pointed out by the static analyzer tool: Error: RESOURCE_LEAK (CWE-772): [#def26] Linux-PAM-1.5.1/modules/pam_filter/pam_filter.c:356: open_fn: Returning handle opened by "open".

* Permit unix_chkpwd & pam_unix.so to run without being setuid-root.Andrew G. Morgan2021-06-291-4/+8
| | | | | | | | | | | | | | | | | | | | | Remove the hard-coding of the idea that the only way pam_unix.so can read the shadow file is if it can, in some way, run setuid-root. Linux capabilities only require cap_dac_override to read the /etc/shadow file. This change achieves two things: it opens a path for a linux-pam application to run without being setuid-root; further, it allows unix_chkpwd to run non-setuid-root if it is installed: sudo setcap cap_dac_override=ep unix_chkpwd If we wanted to link against libcap, we could install this binary with cap_dac_override=p, and use cap_set_proc() to raise the effective bit at runtime. However, some distributions already link unix_chkpwd against libcap-ng for some, likely spurious, reason so "ep" is fine for now. Signed-off-by: Andrew G. Morgan <morgan@kernel.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | sha1 is no longer recommended as a cryptographic algorithm for authentication. Thus, the idea of this change is to replace the implementation provided by hmacsha1 included in pam_timestamp module by the one in the openssl library. This way, there's no need to maintain the cryptographic algorithm implementation and it can be easily changed with a single configuration change. modules/pam_timestamp/hmac_openssl_wrapper.c: implement wrapper functions around openssl's hmac implementation. Moreover, manage the key generation and its read and write in a file. Include an option to configure the cryptographic algorithm in login.defs file. modules/pam_timestamp/hmac_openssl_wrapper.h: likewise. modules/pam_timestamp/pam_timestamp.c: replace calls to functions provided by hmacsha1 by functions provided by openssl's wrapper. configure.ac: include openssl dependecy if it is enabled. modules/pam_timestamp/Makefile.am: include new files and openssl library to compilation. ci/install-dependencies.sh: include openssl library to dependencies.

Make.xml.rules.in: add stringparam profiling for hmac doc/custom-man.xsl: change import docbook to one with profiling modules/pam_timestamp/pam_timestamp.8.xml: add conditional paragraph to indicate the value in /etc/login.defs that holds the value for the encryption algorithm Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1947294
