Package        : systemd
Version        : 215-17+deb8u11
CVE ID         : CVE-2019-3815
Debian Bug     : 924060

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.
