From 3861960837b996d959af504a937a03963dc21d62 Mon Sep 17 00:00:00 2001
From: Alexey Tikhonov <atikhono@redhat.com>

Subject: [PATCH] TOOLS: replace system() with execvp() to avoid execution of
user supplied command
A flaw was found in SSSD, where the sssctl command was vulnerable
to shell command injection via the logs-fetch and cache-expire
subcommands. This flaw allows an attacker to trick the root user
into running a specially crafted sssctl command, such as via sudo,
to gain root access. The highest threat from this vulnerability is
to confidentiality, integrity, as well as system availability.
:fixes: CVE-2021-3621

Subject: [PATCH] ipa: fix reply socket of selinux_child
Commit c92d39a30fa0162d4efdfbe5883c8ea9911a2249 accidentally switched
the reply socket of selinux_child from stdout to stderr while switching
from exec_child to exec_child_ex. This patch returns the original
behavior.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The fix for https://github.com/SSSD/sssd/issues/5528 might discover
domains which are not trusted (one-way trust) or are from a different
forest (direct trust). Both should be ignored because they are not
trusted or can currently not be handled properly. This patch filters out
those domains.

Subject: [PATCH] krb5: AD and IPA don't change Kerberos port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AD and IPA providers use a common fo_server object for LDAP and
Kerberos, which is created with the LDAP data. This means that due to
the changes introduced in
https://github.com/SSSD/sssd/commit/1e747fad4539ffb402010e73f78469fe57af408f
the port in use for the Kerberos requests would be the one specified for
LDAP, usually the default one (389).
In order to avoid that, AD and IPA providers shouldn't change the
Kerberos port with the one provided for LDAP.
:fixes: A critical regression that prevented authentication of users via
AD and IPA providers was fixed. LDAP port was reused for Kerberos
communication and this provider would send incomprehensible information
to this port.

Subject: [PATCH] cache_req: return success for autofs when ENOENT is returned
from provider
The receive function should return true if data provider lookup was
successfull and false if there was an error. "Not found" result is
considered a successful lookup, only failure to perform a search
should result in false return code.

Subject: [PATCH] cache_req: cache_first fix for fully-qualified names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
With commit b572871236a7f9059d375a5ab1bff8cbfd519956 "cache_req:
introduce cache_behavior enumeration" the processing of cache and
backend lookups was refactored. Unfortunately this introduce an issue
when looking up users or groups with a fully-qualified name and the
'cache_first = True' option is set.
In the old code the case when a domain name is available was handle
before the cache_first first option was evaluated and cache_req was
instructed to first look in the cache and then call the backend if the
object is not available or expired, i.e. the default behavior. Since
only a single domain is involved this is in agreement with 'cache_first
= True' and only a single iteration is needed.
In the new code the cache_first option is evaluated before the presence
of a domain name is checked and as a result even for single domain
searches the first cache_req iteration is only looking at the cache and
will not call the backend. This means the now for searches with a
fully-qualified name a second iteration is needed if the object was not
found in the cache.
Unfortunately the old exit condition that if a domain name is present
only a single iteration is needed is still present in the new code which
effectively makes requests with fully-qualified named only search the
cache and never call the backends. This patch removes the exit condition
and does a second iteration for fully-qualified names as well if
'cache_first = True' is set.

Subject: [PATCH] utils: ignore systemd and sd-pam process in
get_active_uid_linux()
We iterate processes in /proc to get the list of active users (users
that has any process running). However, recent change in systemd makes
systemd and sd-pam process ligner for few more seconds when the user has
logged out which breaks the no-session functionality in pam responder.
If user is logged in, another process then systemd and sd-pam must be
running. Therefore we can just ignore these from the list.
```
admin 351997 0.4 0.0 22648 14636 ? Ss 13:25 0:00 /usr/lib/systemd/systemd --user
admin 351999 0.0 0.0 201464 7756 ? S 13:25 0:00 (sd-pam)
```
Resolves: https://github.com/SSSD/sssd/issues/5900
:fixes: Quick log out and log in did not correctly refresh
user's initgroups in `no_session` PAM schema due to lingering
systemd processes.
