CVE-2018-6954

It has been discovered that systemd-tmpfiles mishandles symbolic links present in non-terminal path components. In some configurations a local user could use this vulnerability to get access to arbitrary files when the systemd-tmpfiles command is run. Mitigation There is no known mitigation...

Design/Logic Flaw

systemd-tmpfiles in systemd through 237 mishandles symlinks present in non-terminal path components, which allows local users to obtain ownership of arbitrary files via vectors involving creation of a directory and a file under that directory, and later replacing that directory with a symlink. Th...
