2019-01-14 CVE-2018-16888 It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable. Ubuntu_linux, Active_iq_performance_analytics_services, Element_software, Enterprise_linux, Systemd 4.7
2019-03-21 CVE-2019-6454 An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). Ubuntu_linux, Debian_linux, Fedora, Web_gateway, Active_iq_performance_analytics_services, Leap, Enterprise_linux, Enterprise_linux_compute_node_eus, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian_eus, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_workstation, Systemd 5.5
2019-04-09 CVE-2019-3842 In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any". Debian_linux, Fedora, Enterprise_linux, Systemd 7.0
2019-04-26 CVE-2019-3843 It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled. Ubuntu_linux, Fedora, Cn1610_firmware, Hci_management_node, Snapprotect, Solidfire, Systemd 7.8
2019-04-26 CVE-2019-3844 It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled. Ubuntu_linux, Cn1610_firmware, Hci_management_node, Snapprotect, Solidfire, Systemd 7.8
2019-09-04 CVE-2019-15718 In systemd 240, bus_open_system_watch_bind_with_description in shared/bus-util.c (as used by systemd-resolved to connect to the system D-Bus instance), calls sd_bus_set_trusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that should be restricted to privileged users, in order to change the system's DNS resolver settings. Fedora, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems_8_s390x, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_ibm_z_systems_eus_s390x, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_server_aus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Openshift_container_platform, Systemd 4.4
2016-10-13 CVE-2016-7796 The manager_dispatch_notify_fd function in systemd allows local users to cause a denial of service (system hang) via a zero-length message received over a notify socket, which causes an error to be returned and the notification handler to be disabled. Suse_linux_enterprise_desktop, Suse_linux_enterprise_server, Suse_linux_enterprise_server_for_sap, Suse_linux_enterprise_software_development_kit, Enterprise_linux_desktop, Enterprise_linux_hpc_node, Enterprise_linux_server, Enterprise_linux_workstation, Systemd 5.5
2019-01-11 CVE-2018-16866 An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable. Ubuntu_linux, Debian_linux, Active_iq_performance_analytics_services, Element_software, Enterprise_linux, Enterprise_linux_compute_node_eus, Enterprise_linux_desktop, Enterprise_linux_for_ibm_z_systems_\(Structure_a\), Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_big_endian_eus, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_workstation, Systemd 3.3
2019-01-11 CVE-2018-16864 An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable. Ubuntu_linux, Debian_linux, Communications_session_border_controller, Enterprise_communications_broker, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Systemd 7.8
2019-01-11 CVE-2018-16865 An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when many entries are sent to the journal socket. A local attacker, or a remote one if systemd-journal-remote is used, may use this flaw to crash systemd-journald or execute code with journald privileges. Versions through v240 are vulnerable. Ubuntu_linux, Debian_linux, Communications_session_border_controller, Enterprise_communications_broker, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Systemd 7.8
