Description Laura Pardo 2018-06-26 20:45:29 UTC 
A flaw was found in polkit. 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.
