CVE-2019-6454 (opens in a new tab)Amendment
The SLES security team deemed this advisory irrelevant for SLES:15.0.
NVD Description
Note: Versions mentioned in the description apply only to the upstream systemd-mini-devel package and not the systemd-mini-devel package as distributed by SLES.
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).
