| CVE-2023-26604 | 1 Systemd Project | 1 Systemd | 2023-08-11 | 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-2020-1712 | 2 Redhat, Systemd Project | 6 Ceph Storage, Discovery, Enterprise Linux and 3 more | 2022-06-30 | 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-2017-15908 | 2 Canonical, Systemd Project | 2 Ubuntu Linux, Systemd | 2022-02-20 | 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. | |||||
| CVE-2019-3843 | 4 Canonical, Fedoraproject, Netapp and 1 more | 8 Ubuntu Linux, Fedora, Cn1610 and 5 more | 2022-01-31 | 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-2019-3844 | 3 Canonical, Netapp, Systemd Project | 7 Ubuntu Linux, Cn1610, Cn1610 Firmware and 4 more | 2022-01-31 | 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-2019-3842 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2022-01-31 | 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-2018-16865 | 5 Canonical, Debian, Oracle and 2 more | 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more | 2022-01-31 | 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-2018-16864 | 5 Canonical, Debian, Oracle and 2 more | 11 Ubuntu Linux, Debian Linux, Communications Session Border Controller and 8 more | 2022-01-31 | 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-2018-15688 | 4 Canonical, Debian, Redhat and 1 more | 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more | 2022-01-31 | 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-2018-15687 | 2 Canonical, Systemd Project | 2 Ubuntu Linux, Systemd | 2022-01-31 | 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-2018-15686 | 4 Canonical, Debian, Oracle and 1 more | 4 Ubuntu Linux, Debian Linux, Communications Cloud Native Core Network Function Cloud Native Environment and 1 more | 2022-01-31 | 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-2018-6954 | 3 Canonical, Opensuse, Systemd Project | 3 Ubuntu Linux, Leap, Systemd | 2022-01-31 | 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-2017-18078 | 3 Debian, Opensuse, Systemd Project | 3 Debian Linux, Leap, Systemd | 2022-01-31 | 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-2017-9445 | 1 Systemd Project | 1 Systemd | 2022-01-31 | 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-2017-9217 | 1 Systemd Project | 1 Systemd | 2022-01-31 | 5.0 MEDIUM | 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-2016-10156 | 1 Systemd Project | 1 Systemd | 2017-07-26 | 7.2 HIGH | 7.8 HIGH |
| 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. | |||||
