Fedora 29 : systemd (2019-18b3a10c7f)

Medium Nessus Plugin ID 121138

Synopsis

The remote Fedora host is missing a security update.

Description

- systemd-journald and systemd-journal-remote reject entries which contain too many fields (CVE-2018-16865, #1664973) and set limits on the process' command line length (CVE-2018-16864, #1664972)

- Fix out-of-bounds read when parsing a crafted syslog message in systemd-journald (CVE-2018-16866, #1664975)

- A signal is again used to stop user sessions instead of dbus (#1664491)

No need to log out or reboot.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected systemd package.
