New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Fedora host is missing a security update.

Description

- Fix a local vulnerability from a race condition in chown-recursive (CVE-2018-15687, #1643367)

- Fix a local vulnerability from invalid handling of long lines in state deserialization (CVE-2018-15686, #1643372)

- Fix a remote vulnerability in DHCPv6 in systemd-networkd (CVE-2018-15688, #1643362)

- Downgrade logging of various messages and add loging in other places

- Many many fixes in error handling and minor memory leaks and such

- Fix typos and omissions in documentation

- Various smaller improvements to unit ordering and dependencies

- Handling of invalid (intentionally corrupt) dbus messages is improved, fixing potential local DOS avenues

- The target of symlinks links in .wants/ and .requires/ is now ignored. This fixes an issue where the unit file would sometimes be loaded from such a symlink, leading to non-deterministic unit contents.

- Filtering of kernel threads is improved. This fixes an issues with newer kernels where hybrid kernel/user threads are used by bpfilter.

- Catalog entries for the journal are improved (#1639482)

No need to reboot or log out.
