https://notcve.org/view.php?id=CVE-2019-3843
26 Apr 2019 — 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. Se descubrió que un servicio systemd que utiliza la propiedad DynamicUser puede crear un binario SUID/SGID que podría ejecutarse como servicio transito... • https://www.exploit-db.com/exploits/46760 • CWE-266: Incorrect Privilege Assignment CWE-269: Improper Privilege Management •

https://notcve.org/view.php?id=CVE-2019-3844
25 Apr 2019 — 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.

https://notcve.org/view.php?id=CVE-2019-3842
09 Apr 2019 — 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". En systemd anterior de la versión v242-rc4, fue encontrado que pam_systemd no sanea apropiadamente el entorno anterior usando la variable XDG_... • https://packetstorm.news/files/id/152610 • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 1CVE-2018-16864 – systemd: stack overflow when calling syslog from a command with long cmdline
https://notcve.org/view.php?id=CVE-2018-16864
09 Jan 2019 — 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.

https://notcve.org/view.php?id=CVE-2018-16865
09 Jan 2019 — 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.
