Debian DLA-1711-1 : systemd security update

low Nessus Plugin ID 122826

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected packages.
