    Package        : sssd
    Version        : 2.4.1-2+deb11u1
    CVE ID         : CVE-2021-3621 CVE-2023-3758
    Debian Bug     : 992710 1070369

    Vulnerabilities were found in sssd, a set of daemons to manage access to
    remote directories and authentication mechanisms, which could lead to
    privilege escalation.

    CVE-2021-3621

        It was discovered that the sssctl(8) command was vulnerable to shell
        command injection via the logs-fetch and cache-expire
        subcommands.

        This flaw could allows an attacker to trick the root user into
        running a specially crafted sssctl(8) command, such as via sudo, in
        order to gain root privileges.

    CVE-2023-3758

        A race condition flaw was found in SSSD where the GPO policy is not
        consistently applied for authenticated users.  This may lead to
        improper authorization issues, granting access to resources
        inappropriately.

    For Debian 11 bullseye, these problems have been fixed in version
    2.4.1-2+deb11u1.

    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
