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
2019-05-17 CVE-2018-20839 systemd 242 changes the VT1 mode upon a logout, which allows attackers to read cleartext passwords in certain circumstances, such as watching a shutdown, or using Ctrl-Alt-F1 and Ctrl-Alt-F2. This occurs because the KDGKBMODE (aka current keyboard mode) check is mishandled. Cn1610_firmware, Snapprotect, Solidfire_\&_hci_management_node, Systemd 9.8
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
2020-01-21 CVE-2019-20386 An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur. Ubuntu_linux, Fedora, Active_iq_unified_manager, Cloud_backup, Steelstore_cloud_integrated_storage, Leap, Systemd 2.4
2020-03-31 CVE-2020-1712 A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages. Debian_linux, Ceph_storage, Discovery, Enterprise_linux, Migration_toolkit, Openshift_container_platform, Systemd 7.8
2020-06-03 CVE-2020-13776 systemd through v245 mishandles numerical usernames such as ones composed of decimal digits or 0x followed by hex digits, as demonstrated by use of root privileges when privileges of the 0x0 user account were intended. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000082. Fedora, Active_iq_unified_manager, Solidfire_\&_hci_management_node, Systemd 6.7
2021-05-10 CVE-2020-13529 An exploitable denial-of-service vulnerability exists in Systemd 245. A specially crafted DHCP FORCERENEW packet can cause a server running the DHCP client to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHP ACK packets to reconfigure the server. Fedora, Active_iq_unified_manager, Cloud_backup, Systemd 6.1
2021-07-20 CVE-2021-33910 basic/unit-name.c in systemd prior to 246.15, 247.8, 248.5, and 249.1 has a Memory Allocation with an Excessive Size Value (involving strdupa and alloca for a pathname controlled by a local attacker) that results in an operating system crash. Debian_linux, Fedora, Hci_management_node, Solidfire, Systemd 5.5
