#	CVE ID	CWE ID	Vulnerability Type(s)	Publish Date	Update Date	Score	Gained Access Level	Access	Complexity	Authentication	Conf.	Integ.	Avail.
1	CVE-2023-26604		Exec Code	2023-03-03	2023-05-05	0.0	None	???	???	???	???	???	???
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.
2	CVE-2022-45873	400		2022-11-23	2023-03-01	0.0	None	???	???	???	???	???	???
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.
3	CVE-2022-4415		+Info	2023-01-11	2023-02-02	0.0	None	???	???	???	???	???	???
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.
4	CVE-2022-3821	193	DoS	2022-11-08	2023-05-03	0.0	None	???	???	???	???	???	???
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.
5	CVE-2021-33910	770		2021-07-20	2022-06-14	4.9	None	Local	Low	Not required	None	None	Complete
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.
6	CVE-2021-3997	674	DoS	2022-08-23	2023-05-03	0.0	None	???	???	???	???	???	???
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.
7	CVE-2020-13776	269		2020-06-03	2022-01-31	6.2	None	Local	High	Not required	Complete	Complete	Complete
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.
8	CVE-2020-1712	416	Exec Code	2020-03-31	2022-11-29	4.6	None	Local	Low	Not required	Partial	Partial	Partial
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.
9	CVE-2019-20386	401		2020-01-21	2022-01-28	2.1	None	Local	Low	Not required	None	None	Partial
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.
10	CVE-2019-3844	268		2019-04-26	2022-01-31	4.6	None	Local	Low	Not required	Partial	Partial	Partial
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.
11	CVE-2019-3843	269		2019-04-26	2022-01-31	4.6	None	Local	Low	Not required	Partial	Partial	Partial
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.
12	CVE-2019-3842	863		2019-04-09	2022-01-31	4.4	None	Local	Medium	Not required	Partial	Partial	Partial
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".
13	CVE-2018-21029	295		2019-10-30	2022-07-08	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
DISPUTED 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).
14	CVE-2018-16888	269		2019-01-14	2022-01-31	1.9	None	Local	Medium	Not required	None	None	Partial
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.
15	CVE-2018-16866	200	+Info	2019-01-11	2023-02-13	2.1	None	Local	Low	Not required	Partial	None	None
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.
16	CVE-2018-16865	770	Exec Code	2019-01-11	2023-02-13	4.6	None	Local	Low	Not required	Partial	Partial	Partial
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.
17	CVE-2018-16864	770		2019-01-11	2023-02-13	4.6	None	Local	Low	Not required	Partial	Partial	Partial
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.
18	CVE-2018-15688	120	Overflow	2018-10-26	2022-01-31	5.8	None	Local Network	Low	Not required	Partial	Partial	Partial

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.
20	CVE-2018-15686	502		2018-10-26	2022-01-31	7.2	None	Local	Low	Not required	Complete	Complete	Complete
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.
21	CVE-2018-6954	59		2018-02-13	2022-01-31	7.2	None	Local	Low	Not required	Complete	Complete	Complete
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.
22	CVE-2018-1049	362	DoS	2018-02-16	2022-01-31	4.3	None	Remote	Medium	Not required	None	None	Partial
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.
23	CVE-2017-1000082	269		2017-07-07	2022-01-31	10.0	None	Remote	Low	Not required	Complete	Complete	Complete
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.
24	CVE-2017-18078	59	Bypass	2018-01-29	2022-01-31	4.6	None	Local	Low	Not required	Partial	Partial	Partial
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.
25	CVE-2017-9445	787		2017-06-28	2022-01-31	5.0	None	Remote	Low	Not required	None	None	Partial
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.
26	CVE-2017-9217	476	DoS	2017-05-24	2022-01-31	5.0	None	Remote	Low	Not required	None	None	Partial
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.
