affected by multiple vulnerabilities :

  - Multiple use-after-free errors exist that allow an

    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)");
