Out-of-Bounds write in systemd-networkd dhcpv6 option handling
...
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".
...
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.
...
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.

systemd: reexec state injection: fgets() on overlong lines leads to line splitting
...
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.
...
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.
...
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).
...
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.
