From 7ab83f97e1cbefb78ece17232185bdd2985f0bbe Mon Sep 17 00:00:00 2001

Subject: [PATCH] TOOLS: replace system() with execvp() to avoid execution of
user supplied command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
:relnote: 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.
This patch fixes a flaw by replacing system() with execvp().
:fixes: CVE-2021-3621

Subject: [PATCH] SSSCTL: fix logs-remove when log directory is empty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
"sssctl logs-remove" calls "truncate --size 0 *.log" and "*.log"
will expand to literal '*.log' when directory is empty. The result
is a new empty '*.log' file.
Add '--no-create' to truncate call.
