"A memory leak was discovered in the backport of fixes for
CVE-2018-16864 in systemd-journald.

Function dispatch_message_real() in journald-server.c does not free
allocated memory to store the `_CMDLINE=` entry. A local attacker may
use this flaw to make systemd-journald crash.

Note that as the systemd-journald service is not restarted
automatically a restart of the service or more safely a reboot is
advised.

For Debian 8 'Jessie', this problem has been fixed in version
215-17+deb8u11.

We recommend that you upgrade your systemd packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
