CVE-2017-9217 1 Systemd Project 1 Systemd 2024-12-13 7.5 High
systemd-resolved through 233 allows remote attackers to cause a denial of service (daemon crash) via a crafted DNS response with an empty question section.
CVE-2023-7008 3 Debian, Redhat, Systemd Project 4 Debian Linux, Cryostat, Enterprise Linux and 1 more 2024-11-23 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 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 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-2023-31437 1 Systemd Project 1 Systemd 2024-11-21 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-2023-26604 2 Redhat, Systemd Project 4 Enterprise Linux, Rhel Els, Rhel Eus and 1 more 2024-11-21 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-2022-4415 2 Redhat, Systemd Project 3 Enterprise Linux, Rhel Eus, Systemd 2024-11-21 5.5 Medium
A vulnerability was found in systemd. This security flaw can cause a local information leak due to systemd-coredump not respecting the fs.suid_dumpable kernel setting.
CVE-2022-45873 3 Fedoraproject, Redhat, Systemd Project 3 Fedora, Enterprise Linux, Systemd 2024-11-21 5.5 Medium
systemd 250 and 251 allows local users to achieve a systemd-coredump deadlock by triggering a crash that has a long backtrace. This occurs in parse_elf_object in shared/elf-util.c. The exploitation methodology is to crash a binary calling the same function recursively, and put it in a deeply nested directory to make its backtrace large enough to cause the deadlock. This must be done 16 times when MaxConnections=16 is set for the systemd/units/systemd-coredump.socket file.
CVE-2022-3821 3 Fedoraproject, Redhat, Systemd Project 4 Fedora, Enterprise Linux, Rhel Eus and 1 more 2024-11-21 5.5 Medium
An off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service.
CVE-2022-2526 3 Netapp, Redhat, Systemd Project 14 Active Iq Unified Manager, H300s, H300s Firmware and 11 more 2024-11-21 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 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-2021-33910 5 Debian, Fedoraproject, Netapp and 2 more 8 Debian Linux, Fedora, Hci Management Node and 5 more 2024-11-21 5.5 Medium
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.
CVE-2020-1712 3 Debian, Redhat, Systemd Project 8 Debian Linux, Ceph Storage, Discovery and 5 more 2024-11-21 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-2020-13776 4 Fedoraproject, Netapp, Redhat and 1 more 6 Fedora, Active Iq Unified Manager, Solidfire \& Hci Management Node and 3 more 2024-11-21 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-2020-13529 4 Fedoraproject, Netapp, Redhat and 1 more 5 Fedora, Active Iq Unified Manager, Cloud Backup and 2 more 2024-11-21 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 26 Ubuntu Linux, Debian Linux, Fedora and 23 more 2024-11-21 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 4 Canonical, Netapp, Redhat and 1 more 8 Ubuntu Linux, Cn1610, Cn1610 Firmware and 5 more 2024-11-21 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 5 Canonical, Fedoraproject, Netapp and 2 more 9 Ubuntu Linux, Fedora, Cn1610 and 6 more 2024-11-21 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 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2024-11-21 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-2019-20386 6 Canonical, Fedoraproject, Netapp and 3 more 9 Ubuntu Linux, Fedora, Active Iq Unified Manager and 6 more 2024-11-21 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.
