| CVE-2021-3621 | Hig | 0.57 | 8.8 | 0.03 | Dec 23, 2021 | A flaw was found in SSSD, where 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… | ||
| CVE-2012-3462 | Hig | 0.57 | 8.8 | 0.02 | Dec 26, 2019 | A flaw was found in SSSD version 1.9.0. The SSSD's access-provider logic causes the result of the HBAC rule processing to be ignored in the event that the access-provider is also handling the setup of the user's SELinux user context. | ||
| CVE-2026-68743 | Med | 0.36 | 5.5 | 0.00 | Aug 4, 2026 | A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket,… | ||
| CVE-2026-68742 | Med | 0.36 | 5.5 | 0.00 | Aug 3, 2026 | A flaw was found in SSSD. The sss_nss_protocol_parse_addr() function in the NSS responder does not validate the addrlen field against the remaining packet body size. A local attacker can exploit this via a crafted GETHOSTBYADDR request to the NSS responder socket, causing an… | ||
| CVE-2026-6245 | Med | 0.36 | 5.5 | 0.00 | Apr 15, 2026 | A flaw was found in the System Security Services Daemon (SSSD). The pam_passkey_child_read_data() function within the PAM passkey responder fails to properly handle raw bytes received from a pipe. Because the data is treated as a NUL-terminated C string without explicit… | ||
| CVE-2026-12610 | Med | 0.35 | 6.4 | 0.00 | Jun 30, 2026 | A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to… | ||
| CVE-2018-16838 | Med | 0.35 | 5.4 | 0.01 | Mar 25, 2019 | A flaw was found in sssd Group Policy Objects implementation. When the GPO is not readable by SSSD due to a too strict permission settings on the server side, SSSD will allow all authenticated users to login instead of denying access. | ||
| CVE-2019-3811 | Med | 0.34 | 5.2 | 0.01 | Jan 15, 2019 | 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… | ||
| CVE-2017-12173 | Med | 0.28 | 4.3 | 0.01 | Jul 27, 2018 | 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… | ||
| CVE-2018-10852 | Low | 0.25 | 3.8 | 0.01 | Jun 26, 2018 | 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… | ||
| CVE-2026-68744 | Low | 0.21 | 3.3 | 0.00 | Aug 4, 2026 | A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client. A local attacker… | ||
| CVE-2018-16883 | Low | 0.16 | 2.5 | 0.00 | Dec 19, 2018 | sssd versions from 1.13.0 to before 2.0.0 did not properly restrict access to the infopipe according to the "allowed_uids" configuration parameter. If sensitive information were stored in the user directory, this could be inadvertently disclosed to local attackers. | ||
| CVE-2023-3758 | Hig | 0.00 | 7.1 | 0.01 | Apr 18, 2024 | 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 or denying access to resources inappropriately. | ||
| CVE-2022-4254 | Hig | 0.00 | 8.8 | 0.01 | Feb 1, 2023 | sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters | ||
| CVE-2015-5292 | 0.00 | — | 0.04 | Oct 29, 2015 | 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… | |||
| CVE-2014-0249 | 0.00 | — | 0.00 | Jun 11, 2014 | The System Security Services Daemon (SSSD) 1.11.6 does not properly identify group membership when a non-POSIX group is in a group membership chain, which allows local users to bypass access restrictions via unspecified vectors. | |||
| CVE-2013-0287 | 0.00 | — | 0.02 | Mar 21, 2013 | The Simple Access Provider in System Security Services Daemon (SSSD) 1.9.0 through 1.9.4, when the Active Directory provider is used, does not properly enforce the simple_deny_groups option, which allows remote authenticated users to bypass intended access restrictions. | |||
| CVE-2013-0220 | 0.00 | — | 0.03 | Feb 24, 2013 | The (1) sss_autofs_cmd_getautomntent and (2) sss_autofs_cmd_getautomntbyname function in responder/autofs/autofssrv_cmd.c and the (3) ssh_cmd_parse_request function in responder/ssh/sshsrv_cmd.c in System Security Services Daemon (SSSD) before 1.9.4 allow remote attackers to… | |||
| CVE-2013-0219 | 0.00 | — | 0.00 | Feb 24, 2013 | System Security Services Daemon (SSSD) before 1.9.4, when (1) creating, (2) copying, or (3) removing a user home directory tree, allows local users to create, modify, or delete arbitrary files via a symlink attack on another user's files. | |||
| CVE-2011-1758 | 0.00 | — | 0.00 | May 26, 2011 | The krb5_save_ccname_done function in providers/krb5/krb5_auth.c in System Security Services Daemon (SSSD) 1.5.x before 1.5.7, when automatic ticket renewal and offline authentication are configured, uses a pathname string as a password, which allows local users to bypass… |
