The version of Adobe Flash Player installed on the remote macOS or Mac OS X host is equal or prior to version 32.0.0.371. It is therefore affected by an use after free vulnerability. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to execute arbitrary code within the context of the user.
