- An information disclosure vulnerability exists due to an

can exploit this, by convincing a user to visit a
website containing specially crafted Flash content, to
disclose sensitive information. (CVE-2017-3085)
- A remote code execution vulnerability exists due to
improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit this, by
convincing a user to visit a website containing
specially crafted Flash content, to execute arbitrary
code. (CVE-2017-3106)");
