    <Note Title="Topic" Type="Summary" Ordinal="1" xml:lang="en">Security update for systemd</Note>
    <Note Title="Details" Type="General" Ordinal="2" xml:lang="en">This update for systemd fixes the following issues:

Security issues fixed:

- CVE-2018-6954: Fixed a vulnerability in the symlink handling of systemd-tmpfiles 
  which allowed a local user to obtain ownership of arbitrary files (bsc#1080919).
- CVE-2019-3842: Fixed a vulnerability in pam_systemd which allowed a local user to escalate privileges (bsc#1132348).
- CVE-2019-6454: Fixed a denial of service caused by long dbus messages (bsc#1125352).

Non-security issues fixed:

- systemd-coredump: generate a stack trace of all core dumps (jsc#SLE-5933)
- udevd: notify when max number value of children is reached only once per batch of events (bsc#1132400)
- sd-bus: bump message queue size again (bsc#1132721)
- core: only watch processes when it's really necessary (bsc#955942 bsc#1128657)
- rules: load drivers only on 'add' events (bsc#1126056)
- sysctl: Don't pass null directive argument to '%s' (bsc#1121563)
- Do not automatically online memory on s390x (bsc#1127557)

      <Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">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".</Note>

    <Notes>
      <Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">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).</Note>
