OS X host is equal or prior to version 23.0.0.185. It is, therefore,
affected by an arbitrary code execution vulnerability due to a
use-after-free error. An unauthenticated, remote attacker can exploit
this, by convincing a user to visit a website containing specially
crafted Flash content, to dereference already freed memory, resulting
in the execution of arbitrary code in the context of the current user.");
