A race condition flaw was found in sssd where the GPO policy is not consistently applied for authenticated users

CVE-2023-3758 - April 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.

LDAP Injection

A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection

CVE-2021-3621 8.8 - High - December 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 access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Shell injection

A flaw was found in sssd Group Policy Objects implementation

CVE-2018-16838 5.4 - Medium - March 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.

Improper Privilege Management

A vulnerability was found in sssd

CVE-2019-3811 5.2 - Medium - January 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 directory through chroot() etc. All versions before 2.1 are vulnerable.

sssd versions from 1.13.0 to before 2.0.0 did not properly restrict access to the infopipe according to the "

CVE-2018-16883 5.5 - Medium - December 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-2018-10852 7.5 - High - June 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 versions of SSSD before 1.16.3.

Information Disclosure

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

CVE-2015-5292 - October 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 trigger parsing of PAC blobs during Kerberos authentication.

Resource Management Errors

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

CVE-2013-0220 - February 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 cause a denial of service (out-of-bounds read, crash, and restart) via a crafted SSSD packet.

Buffer Overflow

System Security Services Daemon (SSSD) before 1.9.4, when (1) creating, (2) copying, or (3) removing a user home directory tree

CVE-2013-0219 - February 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.

Permissions, Privileges, and Access Controls

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

CVE-2011-1758 - 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 Kerberos authentication by listing the /tmp directory to obtain the pathname.
