From 0d29e379601819c7f7ed8de18b54de803a9f4049 Mon Sep 17 00:00:00 2001
From: Tomas Mraz <tmraz@fedoraproject.org>
Date: Fri, 5 Sep 2014 09:09:37 +0200
Subject: [PATCH] Add grantor field to audit records of libpam.
The grantor field gives audit trail of PAM modules which granted access
for successful return from libpam calls. In case of failed return
the grantor field is set to '?'.
libpam/pam_account.c (pam_acct_mgmt): Remove _pam_auditlog() call.
libpam/pam_auth.c (pam_authenticate, pam_setcred): Likewise.
libpam/pam_password.c (pam_chauthtok): Likewise.
libpam/pam_session.c (pam_open_session, pam_close_session): Likewise.
libpam/pam_audit.c (_pam_audit_writelog): Add grantors parameter,
add grantor= field to the message if grantors is set.
(_pam_list_grantors): New function creating the string with grantors list.
(_pam_auditlog): Add struct handler pointer parameter, call _pam_list_grantors()
to list the grantors from the handler list.
(_pam_audit_end): Add NULL handler parameter to _pam_auditlog() call.
(pam_modutil_audit_write): Add NULL grantors parameter to _pam_audit_writelog().
libpam/pam_dispatch.c (_pam_dispatch_aux): Set h->grantor where appropriate.
(_pam_clear_grantors): New function to clear grantor field of handler.
(_pam_dispatch): Call _pam_clear_grantors() before executing the stack.
Call _pam_auditlog() when appropriate.
libpam/pam_handlers.c (extract_modulename): Do not allow empty module name
or just "?" to avoid confusing audit trail.
(_pam_add_handler): Test for NULL return from extract_modulename().
Clear grantor field of handler.
libpam/pam_private.h: Add grantor field to struct handler, add handler pointer
parameter to _pam_auditlog().

Subject: [PATCH] pam_userdb: fix password hash comparison
Starting with commit Linux-PAM-0-77-28-g0b3e583 that introduced hashed
passwords support in pam_userdb, hashes are compared case-insensitively.
This bug leads to accepting hashes for completely different passwords in
addition to those that should be accepted.
Additionally, commit Linux-PAM-1_1_6-13-ge2a8187 that added support for
modern password hashes with different lengths and settings, did not
update the hash comparison accordingly, which leads to accepting
computed hashes longer than stored hashes when the latter is a prefix
of the former.
* modules/pam_userdb/pam_userdb.c (user_lookup): Reject the computed
hash whose length differs from the stored hash length.
Compare computed and stored hashes case-sensitively.
Fixes CVE-2013-7041.

Subject: [PATCH] pam_timestamp: fix potential directory traversal issue
(ticket #27)
pam_timestamp uses values of PAM_RUSER and PAM_TTY as components of
the timestamp pathname it creates, so extra care should be taken to
avoid potential directory traversal issues.
* modules/pam_timestamp/pam_timestamp.c (check_tty): Treat
"." and ".." tty values as invalid.
(get_ruser): Treat "." and ".." ruser values, as well as any ruser
value containing '/', as invalid.
Fixes CVE-2014-2583.
