Title:       EGI SVG 'ADVISORY' [TLP:WHITE] Up to 'CRITICAL' risk systemd-journald vulnerabilities [EGI-SVG-2019-15258]  

Date:        2019-01-10 
Updated:     2019-01-15   Updates available therefore Advisory issued.

Affected software and risk
==========================

Up to CRITICAL risk vulnerabilities concerning systemd-journald

Package : systemd-journald
CVE ID  : CVE-2018-16864,CVE-2018-16865,CVE-2018-16866

A set of vulnerabilities in systemd-journald have been reported by Qualys[R 1] which can be used in combination to lead to a 
local root privilege escalation by any local user.

Actions required/recommended
============================

*UPDATE 15/1/2019*: Patches are available for RedHat [R 5], SL [R 6] and CentOS [R 7]. See also individual RedHat CVE 
advisories [R 2][R 3][R 4].

Sites running systemd are urged to update relevant components. This will primarily include sites that use RHEL/CentOS/SL. 
The most urgent hosts to update are worker nodes and UIs where users would typically have access to.

Sites should be aware that if a public exploit is released which allows easy root access in the EGI infrastructure 
this vulnerability is likely to be elevated to 'Critical' and sites will then be required to patch within 7 days or 
risk suspension - Qualys have noted that they will publish a working exploit.

Component installation information
==================================

The RPM installer for the new version of systemd will re-exec the systemd daemon, so a reboot is not required. 
Sites may in addition wish to restart the systemd-journald process using, for example, `systemctl restart systemd-journald`.
