Debian DSA-4367-1 : systemd - security update

high Nessus Plugin ID 121136
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

The Qualys Research Labs discovered multiple vulnerabilities in systemd-journald. Two memory corruption flaws, via attacker-controlled allocations using the alloca function (CVE-2018-16864, CVE-2018-16865 ) and an out-of-bounds read flaw leading to an information leak (CVE-2018-16866 ), could allow an attacker to cause a denial of service or the execution of arbitrary code.

Further details in the Qualys Security Advisory at https://www.qualys.com/2019/01/09/system-down/system-down.txt

Solution

Upgrade the systemd packages.

For the stable distribution (stretch), these problems have been fixed in version 232-25+deb9u7.
