CVE-2019-6454 Open this link in a new tabHow to fix?
Upgrade Debian:12 systemd to version 240-6 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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).
