|---|---|---|---|---|---|
| CVE-2020-13776 | 3 Fedoraproject, Netapp, Systemd Project | 4 Fedora, Active Iq Unified Manager, Solidfire \& Hci Management Node and 1 more | 2024-02-04 | 6.2 MEDIUM | 6.7 MEDIUM |
| 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. | |||||
| CVE-2012-1101 | 1 Systemd Project | 1 Systemd | 2024-02-04 | 2.1 LOW | 5.5 MEDIUM |
| systemd 37-1 does not properly handle non-existent services, which causes a denial of service (failure of login procedure). | |||||
| CVE-2019-20386 | 5 Canonical, Fedoraproject, Netapp and 2 more | 7 Ubuntu Linux, Fedora, Active Iq Unified Manager and 4 more | 2024-02-04 | 2.1 LOW | 2.4 LOW |
| 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. | |||||
| CVE-2019-15718 | 3 Fedoraproject, Redhat, Systemd Project | 14 Fedora, Enterprise Linux, Enterprise Linux Eus and 11 more | 2024-02-04 | 3.6 LOW | 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-2019-3844 | 3 Canonical, Netapp, Systemd Project | 7 Ubuntu Linux, Cn1610, Cn1610 Firmware and 4 more | 2024-02-04 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
| CVE-2019-3843 | 4 Canonical, Fedoraproject, Netapp and 1 more | 8 Ubuntu Linux, Fedora, Cn1610 and 5 more | 2024-02-04 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
| CVE-2019-3842 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2024-02-04 | 4.4 MEDIUM | 7.0 HIGH |
| 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". | |||||
| CVE-2019-6454 | 8 Canonical, Debian, Fedoraproject and 5 more | 22 Ubuntu Linux, Debian Linux, Fedora and 19 more | 2024-02-04 | 4.9 MEDIUM | 5.5 MEDIUM |
| 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). | |||||
| CVE-2018-16864 | 5 Canonical, Debian, Oracle and 2 more | 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more | 2024-02-04 | 4.6 MEDIUM | 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-2018-15686 | 4 Canonical, Debian, Oracle and 1 more | 4 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 1 more | 2024-02-04 | 7.2 HIGH | 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-2018-15688 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more | 2024-02-04 | 5.8 MEDIUM | 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-2018-16888 | 4 Canonical, Netapp, Redhat and 1 more | 5 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 2 more | 2024-02-04 | 1.9 LOW | 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-2018-16865 | 5 Canonical, Debian, Oracle and 2 more | 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more | 2024-02-04 | 4.6 MEDIUM | 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-2018-16866 | 5 Canonical, Debian, Netapp and 2 more | 21 Ubuntu Linux, Debian Linux, Active Iq Performance Analytics Services and 18 more | 2024-02-04 | 2.1 LOW | 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-2018-15687 | 2 Canonical, Systemd Project | 2 Ubuntu Linux, Systemd | 2024-02-04 | 6.9 MEDIUM | 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-2018-1049 | 4 Canonical, Debian, Redhat and 1 more | 11 Ubuntu Linux, Debian Linux, Enterprise Linux and 8 more | 2024-02-04 | 4.3 MEDIUM | 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-2017-18078 | 3 Debian, Opensuse, Systemd Project | 3 Debian Linux, Leap, Systemd | 2024-02-04 | 4.6 MEDIUM | 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-2018-6954 | 3 Canonical, Opensuse, Systemd Project | 3 Ubuntu Linux, Leap, Systemd | 2024-02-04 | 7.2 HIGH | 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-2017-9445 | 1 Systemd Project | 1 Systemd | 2024-02-04 | 5.0 MEDIUM | 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-2017-15908 | 2 Canonical, Systemd Project | 2 Ubuntu Linux, Systemd | 2024-02-04 | 5.0 MEDIUM | 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. | |||||
