Package        : sssd
Version        : 1.15.0-3+deb9u2
CVE ID         : CVE-2021-3621

One security issue has been discovered in sssd.

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.

For Debian 9 stretch, this problem has been fixed in version
1.15.0-3+deb9u2.

We recommend that you upgrade your sssd packages.

For the detailed security status of sssd please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/sssd
