Details

A flaw was found in polkit before version 0.116. The implementation of the polkitbackendinteractiveauthoritycheck_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.
