CVSS: 5.2EPSS: 0%CPEs: 6EXPL: 0CVE-2019-3811 – sssd: fallback_homedir returns '/' for empty home directories in passwd file
https://notcve.org/view.php?id=CVE-2019-3811
A vulnerability was found in sssd. If a user was configured with no home directory set, sssd would return '/' (the root directory) instead of '' (the empty string / no home directory). This could impact services that restrict the user's filesystem access to within their home directory through chroot() etc. All versions before 2.1 are vulnerable.

CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2018-10852 – sssd: information leak from the sssd-sudo responder
https://notcve.org/view.php?id=CVE-2018-10852
The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user. This affects versions of SSSD before 1.16.3. El pipe de Unix que utiliza sudo para contactar SSSD y leer las reglas sudo disponibles desde SSSD tiene permisos demasiado laxos, lo que significa que cualquiera que pueda enviar un mensaje utilizando el mismo protocolo raw que utilizan sudo y SSSD puede leer reglas sudo disponibles para cualquier usuario. Esto afecta a las versiones SSSD en versiones anteriores a la 1.16.3. The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD utilizes too broad of a set of permissions. • http://www.securityfocus.com/bid/104547 https://access.redhat.com/errata/RHSA-2018:3158 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10852 https://lists.debian.org/debian-lts-announce/2018/07/msg00019.html https://access.redhat.com/security/cve/CVE-2018-10852 https://bugzilla.redhat.com/show_bug.cgi?id=1588810 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2017-12173
It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it. Se ha encontrado que la función sysdb_search_user_by_upn_res() de sssd en versiones anteriores a la 1.16.0 no saneaba las peticiones al consultar su caché local y era vulnerable a inyecciones. En un entorno de inicio de sesión centralizado, si un hash de contraseña se almacenaba en la caché local de un usuario determinado, un atacante autenticado podía utilizar este error para recuperarlo.

https://notcve.org/view.php?id=CVE-2015-5292
Memory leak in the Privilege Attribute Certificate (PAC) responder plugin (sssd_pac_plugin.so) in System Security Services Daemon (SSSD) 1.10 before 1.13.1 allows remote authenticated users to cause a denial of service (memory consumption) via a large number of logins that trigger parsing of PAC blobs during Kerberos authentication. Fuga de memoria en el plugin en Privilege Attribute Certificate (PAC) responder (sssd_pac_plugin.so) en System Security Services Daemon (SSSD) 1.10 en versiones anteriores a 1.13.1 permite a usuarios remotos autenticados provocar una denegación de servicio (consumo de memoria) a través de un gran número de logins que desencadenan análisis gramaticales de blobs de PAC durante la autenticación Kerberos. It was found that SSSD's Privilege Attribute Certificate (PAC) responder plug-in would leak a small amount of memory on each authentication request. A remote attacker could potentially use this flaw to exhaust all available memory on the system by making repeated requests to a Kerberized daemon application configured to authenticate using the PAC responder plug-in. • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169110.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169597.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169613.html http://permalink.gmane.org/gmane.linux.redhat.sssd.user/3422 http://rhn.redhat.com/errata/RHSA-2015-2019.html http://rhn.redhat.com/errata/RHSA-2015-2355.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.sec • CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •
