|---|---|---|---|---|---|
| CVE-2016-7795 | 2 Canonical, Systemd Project | 2 Ubuntu Linux, Systemd | 2025-04-12 | 4.9 MEDIUM | 5.5 MEDIUM |
| 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-2013-4327 | 3 Canonical, Debian, Systemd Project | 3 Ubuntu Linux, Debian Linux, Systemd | 2025-04-11 | 6.9 MEDIUM | N/A |
| systemd does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288. | |||||
| CVE-2013-4394 | 2 Debian, Systemd Project | 2 Debian Linux, Systemd | 2025-04-11 | 5.9 MEDIUM | N/A |
| The SetX11Keyboard function in systemd, when PolicyKit Local Authority (PKLA) is used to change the group permissions on the X Keyboard Extension (XKB) layouts description, allows local users in the group to modify the Xorg X11 Server configuration file and possibly gain privileges via vectors involving "special and control characters." | |||||
| CVE-2013-4391 | 2 Debian, Systemd Project | 2 Debian Linux, Systemd | 2025-04-11 | 7.5 HIGH | N/A |
| Integer overflow in the valid_user_field function in journal/journald-native.c in systemd allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large journal data field, which triggers a heap-based buffer overflow. | |||||
| CVE-2013-4393 | 1 Systemd Project | 1 Systemd | 2025-04-11 | 2.1 LOW | N/A |
| journald in systemd, when the origin of native messages is set to file, allows local users to cause a denial of service (logging service blocking) via a crafted file descriptor. | |||||
| CVE-2023-26604 | 1 Systemd Project | 1 Systemd | 2025-03-07 | N/A | 7.8 HIGH |
| systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output. | |||||
| CVE-2023-31437 | 1 Systemd Project | 1 Systemd | 2025-01-03 | N/A | 5.3 MEDIUM |
| An issue was discovered in systemd 253. An attacker can modify a sealed log file such that, in some views, not all existing and sealed log messages are displayed. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." | |||||
| CVE-2023-7008 | 2 Debian, Systemd Project | 2 Debian Linux, Systemd | 2024-11-22 | N/A | 5.9 MEDIUM |
| A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records. | |||||
| CVE-2023-31439 | 1 Systemd Project | 1 Systemd | 2024-11-21 | N/A | 5.3 MEDIUM |
| An issue was discovered in systemd 253. An attacker can modify the contents of past events in a sealed log file and then adjust the file such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." | |||||
| CVE-2023-31438 | 1 Systemd Project | 1 Systemd | 2024-11-21 | N/A | 5.3 MEDIUM |
| An issue was discovered in systemd 253. An attacker can truncate a sealed log file and then resume log sealing such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." | |||||
| CVE-2022-2526 | 2 Netapp, Systemd Project | 10 Active Iq Unified Manager, H300s, H300s Firmware and 7 more | 2024-11-21 | N/A | 9.8 CRITICAL |
| A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later. | |||||
| CVE-2021-3997 | 3 Fedoraproject, Redhat, Systemd Project | 3 Fedora, Enterprise Linux, Systemd | 2024-11-21 | N/A | 5.5 MEDIUM |
| A flaw was found in systemd. An uncontrolled recursion in systemd-tmpfiles may lead to a denial of service at boot time when too many nested directories are created in /tmp. | |||||
| CVE-2020-1712 | 3 Debian, Redhat, Systemd Project | 7 Debian Linux, Ceph Storage, Discovery and 4 more | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| 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. | |||||
| CVE-2020-13529 | 3 Fedoraproject, Netapp, Systemd Project | 4 Fedora, Active Iq Unified Manager, Cloud Backup and 1 more | 2024-11-21 | 2.9 LOW | 6.1 MEDIUM |
| 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. | |||||
| CVE-2019-6454 | 8 Canonical, Debian, Fedoraproject and 5 more | 22 Ubuntu Linux, Debian Linux, Fedora and 19 more | 2024-11-21 | 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-2019-3844 | 3 Canonical, Netapp, Systemd Project | 7 Ubuntu Linux, Cn1610, Cn1610 Firmware and 4 more | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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-2019-15718 | 3 Fedoraproject, Redhat, Systemd Project | 14 Fedora, Enterprise Linux, Enterprise Linux Eus and 11 more | 2024-11-21 | 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-2018-21029 | 2 Fedoraproject, Systemd Project | 2 Fedora, Systemd | 2024-11-21 | 7.5 HIGH | 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) | |||||
