"details": "Jakub Hrozek discovered that SSSD incorrectly handled file permissions. A\nlocal attacker could possibly use this issue to read the sudo rules\navailable for any user. This issue only affected Ubuntu 18.04 LTS.\n(CVE-2018-10852)\n\nIt was discovered that SSSD incorrectly handled Group Policy Objects. When\nSSSD is configured with too strict permissions causing the GPO to not be\nreadable, SSSD will allow all authenticated users to login instead of being\ndenied, contrary to expectations. This issue only affected Ubuntu 18.04\nLTS. (CVE-2018-16838)\n\nIt was discovered that SSSD incorrectly handled users with no home\ndirectory set. When no home directory was set, SSSD would return the root\ndirectory instead of an empty string, possibly bypassing security measures.\nThis issue only affected Ubuntu 18.04 LTS. (CVE-2019-3811)\n\nCedric Buissart discovered that SSSD incorrectly handled the sssctl\ncommand. In certain environments, a local user could use this issue to\nexecute arbitrary commands and possibly escalate privileges.\n(CVE-2021-3621)\n",
