The version of Adobe Flash Player installed on the remote Windows host is equal or prior to version 24.0.0.194. It is, therefore, affected by multiple vulnerabilities :
Multiple use-after-free errors exist that allow an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-2982, CVE-2017-2985, CVE-2017-2993, CVE-2017-2994).
Multiple heap buffer overflow conditions exist that allow an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-2984, CVE-2017-2986, CVE-2017-2992).
An integer overflow condition exists that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-2987).
Multiple memory corruption issues exist that allow an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-2988, CVE-2017-2990, CVE-2017-2991, CVE-2017-2996).
A type confusion error exists that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-2995)
