2019-10-30 CVE-2018-21029 systemd 239 through 243 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication (SNI) is not sent, and there is no hostname validation with the GnuTLS backend. Systemd N/A
2018-10-26 CVE-2018-15688 A buffer overflow vulnerability in the dhcp6 client of systemd allows a malicious dhcp6 server to overwrite heap memory in systemd-networkd. Affected releases are systemd: versions up to and including 239. Ubuntu_linux, Debian_linux, Systemd, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation 9.8
2018-10-26 CVE-2018-15687 A race condition in chown_one() of systemd allows an attacker to cause systemd to set arbitrary permissions on arbitrary files. Affected releases are systemd versions up to and including 239. Ubuntu_linux, Systemd 4.7
2018-02-16 CVE-2018-1049 In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted. Ubuntu_linux, Debian_linux, Systemd, Enterprise_linux, Enterprise_linux_aus, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_eus, Enterprise_linux_server_tus, Enterprise_linux_workstation 5.9
2018-01-29 CVE-2017-18078 systemd-tmpfiles in systemd before 237 attempts to support ownership/permission changes on hardlinked files even if the fs.protected_hardlinks sysctl is turned off, which allows local users to bypass intended access restrictions via vectors involving a hard link to a file for which the user lacks write access, as demonstrated by changing the ownership of the /etc/passwd file. Debian_linux, Systemd, Leap 7.8
2017-10-26 CVE-2017-15908 In systemd 223 through 235, a remote DNS server can respond with a custom crafted DNS NSEC resource record to trigger an infinite loop in the dns_packet_read_type_window() function of the 'systemd-resolved' service and cause a DoS of the affected service. Systemd 7.5
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, Systemd 5.5
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, Systemd, 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, Virtualization 7.8
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, Systemd, 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, Virtualization 7.8
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. Systemd, Active_iq_performance_analytics_services, Element_software, Enterprise_linux 4.7
