FEDORA-2018-c402eea18b — security update for systemd

stable

systemd-239-6.git9f3aed1.fc29

FEDORA-2018-c402eea18b created by zbyszek 7 years ago for Fedora 29

Fix a local vulnerability from a race condition in chown-recursive (CVE-2018-15687, #1639076)
Fix a local vulnerability from invalid handling of long lines in state deserialization (CVE-2018-15686, #1639071)
Fix a remote vulnerability in DHCPv6 in systemd-networkd (CVE-2018-15688, #1639067)
The DHCP server is started only when link is UP
DHCPv6 prefix delegation is improved
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
Typo in %%_environmnentdir rpm macro is fixed (with backwards compatiblity preserved)
Matching by MACAddress= in systemd-networkd is fixed
Creation of user runtime directories is improved, and the user manager is only stopped after 10 s after the user logs out (#1642460 and other bugs)
systemd units systemd-timesyncd, systemd-resolved, systemd-networkd are switched back to use DynamicUser=0
Aliases are now resolved when loading modules from pid1. This is a (redundant) fix for a brief kernel regression.
"systemctl --wait start" exits immediately if no valid units are named
zram devices are not considered as candidates for hibernation
ECN is not requested for both in- and out-going connections (the sysctl overide for net.ipv4.tcp_ecn is removed)
Various smaller improvements to unit ordering and dependencies
generators are now called with the manager's environment
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.
"noresume" can be used on the kernel command line to force normal boot even if a hibernation images is present
Hibernation is not advertised if resume= is not present on the kernenl command line
Hibernation/Suspend/... modes can be disabled using AllowSuspend=, AllowHibernation=, AllowSuspendThenHibernate=, AllowHybridSleep=
LOGO= and DOCUMENTATION_URL= are documented for the os-release file
The hashmap mempool is now only used internally in systemd, and is disabled for external users of the systemd libraries
Additional state is serialized/deserialized when logind is restarted, fixing the handling of user objects
Catalog entries for the journal are improved (#1639482)
If suspend fails, the post-suspend hooks are still called.
Various build issues on less-common architectures are fixed

No need to reboot or log out.

I have /var installed on a sepatate partition and after this update Setroubleshoot produces following messages:

SELinux is preventing systemd-logind from read access on the blk_file
SELinux is preventing systemd-logind from open access on the blk_file
SELinux is preventing systemd-logind from ioctl access on the blk_file

I upgraded to systemd-239-6.git9f3aed1.fc29 from Koji. When I logged into Plasma twice after the systemd update, I saw the following denial of systemd-user-ru reading dbus-1 both times. I put the details in the report at https://bugzilla.redhat.com/show_bug.cgi?id=1644313 systemd seems to be running normally otherwise.

As it revealed later, Setroubleshoot messages I mentioned above were referred not to /var, but to UEFI BIOS partition.
