* Release version 1.2.1Thorsten Kukuk2015-06-225-11/+33
| | | | | | | | | | | | | | | | | | | | | | | | 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

* Introduce pam_modutil_sanitize_helper_fdsDmitry V. Levin2014-01-274-37/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces pam_modutil_sanitize_helper_fds - a new function that redirects standard descriptors and closes all other descriptors. pam_modutil_sanitize_helper_fds supports three types of input and output redirection: - PAM_MODUTIL_IGNORE_FD: do not redirect at all. - PAM_MODUTIL_PIPE_FD: redirect to a pipe. For stdin, it is implemented by creating a pipe, closing its write end, and redirecting stdin to its read end. Likewise, for stdout/stderr it is implemented by creating a pipe, closing its read end, and redirecting to its write end. Unlike stdin redirection, stdout/stderr redirection to a pipe has a side effect that a process writing to such descriptor should be prepared to handle SIGPIPE appropriately. - PAM_MODUTIL_NULL_FD: redirect to /dev/null. For stdin, it is implemented via PAM_MODUTIL_PIPE_FD because there is no functional difference. For stdout/stderr, it is classic redirection to /dev/null. PAM_MODUTIL_PIPE_FD is usually more suitable due to linux kernel security restrictions, but when the helper process might be writing to the corresponding descriptor and termination of the helper process by SIGPIPE is not desirable, one should choose PAM_MODUTIL_NULL_FD. * libpam/pam_modutil_sanitize.c: New file. * libpam/Makefile.am (libpam_la_SOURCES): Add it. * libpam/include/security/pam_modutil.h (pam_modutil_redirect_fd, pam_modutil_sanitize_helper_fds): New declarations. * libpam/libpam.map (LIBPAM_MODUTIL_1.1.9): New interface. * modules/pam_exec/pam_exec.c (call_exec): Use pam_modutil_sanitize_helper_fds. * modules/pam_mkhomedir/pam_mkhomedir.c (create_homedir): Likewise. * modules/pam_unix/pam_unix_acct.c (_unix_run_verify_binary): Likewise. * modules/pam_unix/pam_unix_passwd.c (_unix_run_update_binary): Likewise. * modules/pam_unix/support.c (_unix_run_helper_binary): Likewise. * modules/pam_xauth/pam_xauth.c (run_coprocess): Likewise. * modules/pam_unix/support.h (MAX_FD_NO): Remove.
* Fix gratuitous use of strdup and x_strdupDmitry V. Levin2014-01-273-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | There is no need to copy strings passed as arguments to execve, the only potentially noticeable effect of using strdup/x_strdup would be a malformed argument list in case of memory allocation error. Also, x_strdup, being a thin wrapper around strdup, is of no benefit when its argument is known to be non-NULL, and should not be used in such cases. * modules/pam_cracklib/pam_cracklib.c (password_check): Use strdup instead of x_strdup, the latter is of no benefit in this case. * modules/pam_ftp/pam_ftp.c (lookup): Likewise. * modules/pam_userdb/pam_userdb.c (user_lookup): Likewise. * modules/pam_userdb/pam_userdb.h (x_strdup): Remove. * modules/pam_mkhomedir/pam_mkhomedir.c (create_homedir): Do not use x_strdup for strings passed as arguments to execve. * modules/pam_unix/pam_unix_acct.c (_unix_run_verify_binary): Likewise. * modules/pam_unix/pam_unix_passwd.c (_unix_run_update_binary): Likewise. * modules/pam_unix/support.c (_unix_run_helper_binary): Likewise.

* pam_unix: make configuration consistent in --enable-static-modules modeDmitry V. Levin2012-02-037-71/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In --enable-static-modules mode, it was not possible to use "pam_unix" in PAM config files. Instead, different names had to be used for each management group: pam_unix_auth, pam_unix_acct, pam_unix_passwd and pam_unix_session. This change makes pam_unix configuration consistent with other PAM modules. * README: Remove the paragraph describing pam_unix distinctions in --enable-static-modules mode. * libpam/pam_static_modules.h (_pam_unix_acct_modstruct, _pam_unix_auth_modstruct, _pam_unix_passwd_modstruct, _pam_unix_session_modstruct): Remove.

Instead, it recommends to write the file name of the library explicitly, and use -l option only to list third-party libraries. As result, the default value of *_DEPENDENCIES will list all local libraries and omit the other ones. * modules/pam_access/Makefile.am (pam_access_la_LIBADD): Replace "-L$(top_builddir)/libpam -lpam" with "$(top_builddir)/libpam/libpam.la", to follow GNU automake recommendations. * modules/pam_cracklib/Makefile.am (pam_cracklib_la_LIBADD): Likewise. * modules/pam_debug/Makefile.am (pam_debug_la_LIBADD): Likewise. * modules/pam_deny/Makefile.am (pam_deny_la_LIBADD): Likewise. * modules/pam_echo/Makefile.am (pam_echo_la_LIBADD): Likewise. * modules/pam_env/Makefile.am (pam_env_la_LIBADD): Likewise. * modules/pam_exec/Makefile.am (pam_exec_la_LIBADD): Likewise. * modules/pam_faildelay/Makefile.am (pam_faildelay_la_LIBADD): Likewise. * modules/pam_filter/Makefile.am (pam_filter_la_LIBADD): Likewise. * modules/pam_filter/upperLOWER/Makefile.am (LDADD): Likewise. * modules/pam_ftp/Makefile.am (pam_ftp_la_LIBADD): Likewise. * modules/pam_group/Makefile.am (pam_group_la_LIBADD): Likewise. * modules/pam_issue/Makefile.am (pam_issue_la_LIBADD): Likewise. * modules/pam_keyinit/Makefile.am (pam_keyinit_la_LIBADD): Likewise. * modules/pam_lastlog/Makefile.am (pam_lastlog_la_LIBADD): Likewise. * modules/pam_limits/Makefile.am (pam_limits_la_LIBADD): Likewise. * modules/pam_listfile/Makefile.am (pam_listfile_la_LIBADD): Likewise. * modules/pam_localuser/Makefile.am (pam_localuser_la_LIBADD): Likewise. * modules/pam_loginuid/Makefile.am (pam_loginuid_la_LIBADD): Likewise. * modules/pam_mail/Makefile.am (pam_mail_la_LIBADD): Likewise. * modules/pam_mkhomedir/Makefile.am (pam_mkhomedir_la_LIBADD, mkhomedir_helper_LDADD): Likewise. * modules/pam_motd/Makefile.am (pam_motd_la_LIBADD): Likewise. * modules/pam_namespace/Makefile.am (pam_namespace_la_LIBADD): Likewise. * modules/pam_nologin/Makefile.am (pam_nologin_la_LIBADD): Likewise. * modules/pam_permit/Makefile.am (pam_permit_la_LIBADD): Likewise. * modules/pam_pwhistory/Makefile.am (pam_pwhistory_la_LIBADD): Likewise. * modules/pam_rhosts/Makefile.am (pam_rhosts_la_LIBADD): Likewise. * modules/pam_rootok/Makefile.am (pam_rootok_la_LIBADD): Likewise. * modules/pam_securetty/Makefile.am (pam_securetty_la_LIBADD): Likewise. * modules/pam_sepermit/Makefile.am (pam_sepermit_la_LIBADD): Likewise. * modules/pam_shells/Makefile.am (pam_shells_la_LIBADD): Likewise. * modules/pam_stress/Makefile.am (pam_stress_la_LIBADD): Likewise. * modules/pam_succeed_if/Makefile.am (pam_succeed_if_la_LIBADD): Likewise. * modules/pam_tally/Makefile.am (pam_tally_la_LIBADD): Likewise. * modules/pam_tally2/Makefile.am (pam_tally2_la_LIBADD, pam_tally2_LDADD): Likewise. * modules/pam_time/Makefile.am (pam_time_la_LIBADD): Likewise. * modules/pam_timestamp/Makefile.am (pam_timestamp_la_LIBADD, pam_timestamp_check_LDADD, hmacfile_LDADD): Likewise. * modules/pam_tty_audit/Makefile.am (pam_tty_audit_la_LIBADD): Likewise. * modules/pam_umask/Makefile.am (pam_umask_la_LIBADD): Likewise. * modules/pam_unix/Makefile.am (pam_unix_la_LIBADD): Likewise. * modules/pam_userdb/Makefile.am (pam_userdb_la_LIBADD): Likewise. * modules/pam_warn/Makefile.am (pam_warn_la_LIBADD): Likewise. * modules/pam_wheel/Makefile.am (pam_wheel_la_LIBADD): Likewise. * modules/pam_xauth/Makefile.am (pam_xauth_la_LIBADD): Likewise. * tests/Makefile.am (LDADD): Likewise. * examples/Makefile.am (LDADD): Replace "-L$(top_builddir)/libpam -lpam" with "$(top_builddir)/libpam/libpam.la", and "-L$(top_builddir)/libpam_misc -lpam_misc" with "$(top_builddir)/libpam_misc/libpam_misc.la", to follow GNU automake recommendations. * xtests/Makefile.am (LDADD): Likewise. * modules/pam_selinux/Makefile.am (pam_selinux_la_LIBADD): Likewise.
