CVE-2019-15718 3 Fedoraproject, Redhat, Systemd Project 15 Fedora, Enterprise Linux, Enterprise Linux Eus and 12 more 2024-11-21 4.4 Medium
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.
CVE-2018-6954 3 Canonical, Opensuse, Systemd Project 3 Ubuntu Linux, Leap, Systemd 2024-11-21 7.8 High
systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. This occurs even if the fs.protected_symlinks sysctl is turned on.
CVE-2018-21029 2 Fedoraproject, Systemd Project 2 Fedora, Systemd 2024-11-21 9.8 Critical
systemd 239 through 245 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. NOTE: This has been disputed by the developer as not a vulnerability since hostname validation does not have anything to do with this issue (i.e. there is no hostname to be sent)
CVE-2018-20839 2 Netapp, Systemd Project 5 Cn1610, Cn1610 Firmware, Snapprotect and 2 more 2024-11-21 4.3 Medium
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.
CVE-2018-1049 4 Canonical, Debian, Redhat and 1 more 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more 2024-11-21 5.9 Medium
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.
CVE-2018-16888 4 Canonical, Netapp, Redhat and 1 more 6 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 3 more 2024-11-21 4.7 Medium
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.
CVE-2018-16866 5 Canonical, Debian, Netapp and 2 more 26 Ubuntu Linux, Debian Linux, Active Iq Performance Analytics Services and 23 more 2024-11-21 3.3 Low
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.
CVE-2018-16865 5 Canonical, Debian, Oracle and 2 more 16 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 13 more 2024-11-21 7.8 High
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.
CVE-2018-16864 5 Canonical, Debian, Oracle and 2 more 16 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 13 more 2024-11-21 7.8 High
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.
CVE-2018-15688 4 Canonical, Debian, Redhat and 1 more 10 Ubuntu Linux, Debian Linux, Enterprise Linux and 7 more 2024-11-21 8.8 High
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.
CVE-2018-15687 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2024-11-21 7.0 High
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.
CVE-2018-15686 5 Canonical, Debian, Oracle and 2 more 10 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 7 more 2024-11-21 7.8 High
A vulnerability in unit_deserialize of systemd allows an attacker to supply arbitrary state across systemd re-execution via NotifyAccess. This can be used to improperly influence systemd execution and possibly lead to root privilege escalation. Affected releases are systemd versions up to and including 239.
CVE-2017-9445 1 Systemd Project 1 Systemd 2024-11-21 7.5 High
In systemd through 233, certain sizes passed to dns_packet_new in systemd-resolved can cause it to allocate a buffer that's too small. A malicious DNS server can exploit this via a response with a specially crafted TCP payload to trick systemd-resolved into allocating a buffer that's too small, and subsequently write arbitrary data beyond the end of it.
CVE-2017-18078 3 Debian, Opensuse, Systemd Project 3 Debian Linux, Leap, Systemd 2024-11-21 7.8 High
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.
CVE-2017-15908 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2024-11-21 7.5 High
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.
CVE-2017-1000082 1 Systemd Project 1 Systemd 2024-11-21 9.8 Critical
systemd v233 and earlier fails to safely parse usernames starting with a numeric digit (e.g. "0day"), running the service in question with root privileges rather than the user intended.
CVE-2016-7796 3 Novell, Redhat, Systemd Project 11 Suse Linux Enterprise Desktop, Suse Linux Enterprise Server, Suse Linux Enterprise Server For Sap and 8 more 2024-11-21 N/A
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.
CVE-2016-7795 3 Canonical, Redhat, Systemd Project 4 Ubuntu Linux, Enterprise Linux, Rhel Eus and 1 more 2024-11-21 N/A
The manager_invoke_notify_message function in systemd 231 and earlier allows local users to cause a denial of service (assertion failure and PID 1 hang) via a zero-length message received over a notify socket.
CVE-2016-10156 1 Systemd Project 1 Systemd 2024-11-21 N/A
A flaw in systemd v228 in /src/basic/fs-util.c caused world writable suid files to be created when using the systemd timers features, allowing local attackers to escalate their privileges to root. This is fixed in v229.
CVE-2015-7510 1 Systemd Project 1 Systemd 2024-11-21 N/A
Stack-based buffer overflow in the getpwnam and getgrnam functions of the NSS module nss-mymachines in systemd.
