Affected Packages:

systemd

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 924060.
In Mitre's CVE dictionary: CVE-2019-3815.

More information:

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.
