However, the fix for\nCVE-2018-6954 was not sufficient. This update provides the remaining fixes.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n Jann Horn discovered that unit_deserialize incorrectly handled status messages\n above a certain length. A local attacker could potentially exploit this via\n NotifyAccess to inject arbitrary state across re-execution and obtain root\n privileges. (CVE-2018-15686)\n \n Jann Horn discovered a race condition in chown_one(). A local attacker\n could potentially exploit this by setting arbitrary permissions on certain\n files to obtain root privileges. This issue only affected Ubuntu 18.04 LTS\n and Ubuntu 18.10. (CVE-2018-15687)\n \n It was discovered that systemd-tmpfiles mishandled symlinks in\n non-terminal path components. A local attacker could potentially exploit\n this by gaining ownership of certain files to obtain root privileges. This\n issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
