+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
