"In the recently uploaded systemd security update (215-17+deb8u12 via
DLA-1762-1), a regression was discovered in the fix for
CVE-2017-18078.

The observation of Debian jessie LTS users was, that after upgrading
to

+deb8u12 temporary files would not have the correct ownerships and
permissions anymore (instead of a file being owned by a specific user
and/or group, files were being owned by root:root; setting POSIX file
permissions (rwx, etc.) was also affected).

For Debian 8 'Jessie', this regression problem has been fixed in
version 215-17+deb8u13.

We recommend that you upgrade your systemd packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
