Security update for systemd

This update for systemd fixes the following issues:

  • CVE-2019-6454: Overlong DBUS messages could be used to crash systemd (bsc#1125352)

  • units: make sure initrd-cleanup.service terminates before switching to rootfs (bsc#1123333)

  • logind: fix bad error propagation

  • login: log session state 'closing' (as well as New/Removed)

  • logind: fix borked r check

  • login: don't remove all devices from PID1 when only one was removed

  • login: we only allow opening character devices

  • login: correct comment in session_device_free()

  • login: remember that fds received from PID1 need to be removed eventually

  • login: fix FDNAME in call to sd_pid_notify_with_fds()

  • logind: fd 0 is a valid fd

  • logind: rework sd_eviocrevoke()

  • logind: check file is device node before using .st_rdev

  • logind: use the new FDSTOREREMOVE=1 sd_notify() message (bsc#1124153)

  • core: add a new sd_notify() message for removing fds from the FD store again

  • logind: make sure we don't trip up on half-initialized session devices (bsc#1123727)

  • fd-util: accept that kcmp might fail with EPERM/EACCES

  • core: Fix use after free case in load_from_path() (bsc#1121563)

  • core: include Found state in device dumps

  • device: fix serialization and deserialization of DeviceFound

  • fix path in btrfs rule (#6844)

  • assemble multidevice btrfs volumes without external tools (#6607) (bsc#1117025)

  • Update systemd-system.conf.xml (bsc#1122000)

  • units: inform user that the default target is started after exiting from rescue or emergency mode

  • core: free lines after reading them (bsc#1123892)

  • sd-bus: if we receive an invalid dbus message, ignore and proceeed

Описание

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).
