CVSS: 8.8EPSS: 0%CPEs: 10EXPL: 0CVE-2017-12173 – sssd: unsanitized input when searching in local cache database
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. It was found that sssd's sysdb_search_user_by_upn_res() function did not sanitize requests when querying its local cache and was vulnerable to injection. • https://access.redhat.com/errata/RHSA-2017:3379 https://access.redhat.com/errata/RHSA-2018:1877 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-12173 https://access.redhat.com/security/cve/CVE-2017-12173 https://bugzilla.redhat.com/show_bug.cgi?id=1498173 • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 6.8EPSS: 1%CPEs: 17EXPL: 0CVE-2015-5292 – sssd: memory leak in the sssd_pac_plugin
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 •
