CVE-2018-1116 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:12.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream policykit-1 package and not the policykit-1 package as distributed by Ubuntu.
A flaw was found in polkit before version 0.116. The implementation of the polkit_backend_interactive_authority_check_authorization function in polkitd allows to test for authentication and trigger authentication of unrelated processes owned by other users. This may result in a local DoS and information disclosure.
