The remote host is running a version of macOS that is 10.12.x prior to 10.12.5. It is, therefore, affected by multiple vulnerabilities :

  • Multiple memory corruption issues exist in the Kernel component that allow a local attacker to gain kernel-level privileges. (CVE-2017-2494, CVE-2017-2546)

  • A state management flaw exists in the iBooks component due to improper handling of URLs. An unauthenticated, remote attacker can exploit this, via a specially crafted book, to open arbitrary websites without user permission. (CVE-2017-2497)

  • A local privilege escalation vulnerability exists in the Kernel component due to a race condition. A local attacker can exploit this to execute arbitrary code with kernel-level privileges. (CVE-2017-2501)

  • An information disclosure vulnerability exists in the CoreAudio component due to improper sanitization of user-supplied input. A local attacker can exploit this to read the contents of restricted memory.
    (CVE-2017-2502)

  • A memory corruption issue exists in the Intel graphics driver component that allows a local attacker to execute arbitrary code with kernel-level privileges.
    CVE-2017-2503)

  • Multiple information disclosure vulnerabilities exist in the Kernel component due to improper sanitization of user-supplied input. A local attacker can exploit these to read the contents of restricted memory.
    (CVE-2017-2507, CVE-2017-2509, CVE-2017-2516, CVE-2017-6987)

  • A memory corruption issue exists in the Sandbox component that allows an unauthenticated, remote attacker to escape an application sandbox.
    (CVE-2017-2512)

  • A use-after-free error exists in the SQLite component when handling SQL queries. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in the execution of arbitrary code.
    (CVE-2017-2513)

  • Multiple buffer overflow conditions exist in the SQLite component due to the improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these, via a specially crafted SQL query, to execute arbitrary code. (CVE-2017-2518, CVE-2017-2520)

  • A memory corruption issue exists in the SQLite component when handling SQL queries. An unauthenticated, remote attacker can exploit this, via a specially crafted SQL query, to execute arbitrary code. (CVE-2017-2519)

  • An unspecified memory corruption issue exists in the TextInput component when parsing specially crafted data.
    An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-2524)

  • A flaw exists in the CoreAnimation component when handling specially crafted data. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-2527)

  • A race condition exists in the DiskArbitration feature that allow a local attacker to gain system-level privileges. (CVE-2017-2533)

  • An unspecified flaw exists in the Speech Framework that allows a local attacker to escape an application sandbox. (CVE-2017-2534)

  • A resource exhaustion issue exists in the Security component due to improper validation of user-supplied input. A local attacker can exploit this to exhaust resources and escape an application sandbox.
    (CVE-2017-2535)

  • Multiple memory corruption issues exist in the WindowServer component that allow a local attacker to execute arbitrary code with system-level privileges.
    (CVE-2017-2537, CVE-2017-2548)

  • An information disclosure vulnerability exists in WindowServer component in the _XGetConnectionPSN() function due to improper validation of user-supplied input. A local attacker can exploit this to read the contents of restricted memory. (CVE-2017-2540)

  • A stack-based buffer overflow condition exists in the WindowServer component in the _XGetWindowMovementGroup() function due to improper validation of user-supplied input. A local attacker can exploit this to execute arbitrary code with the privileges of WindowServer.
    (CVE-2017-2541)

  • Multiple memory corruption issues exist in the Multi-Touch component that allow a local attacker to execute arbitrary code with kernel-level privileges.
    (CVE-2017-2542, CVE-2017-2543)

  • A use-after-free error exists in the IOGraphic component that allows a local attacker to execute arbitrary code with kernel-level privileges. (CVE-2017-2545)

  • A flaw exists in the Speech Framework, specifically within the speechsynthesisd service, due to improper validation of unsigned dynamic libraries (.dylib) before being loaded. A local attacker can exploit this to bypass the application’s sandbox and execute arbitrary code with elevated privileges. (CVE-2017-6977)

  • A memory corruption issue exists in the Accessibility Framework that allows a local attacker to execute arbitrary code with system-level privileges.
    (CVE-2017-6978)

  • A race condition exists in the IOSurface component that allows a local attacker to execute arbitrary code with kernel-level privileges. (CVE-2017-6979)

  • A logic error exists in the iBooks component due to improper path validation for symlinks. A local attacker can exploit this to execute arbitrary code with root privileges. (CVE-2017-6981)

  • Multiple memory corruption issues exist in SQLite due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website, to execute arbitrary code. (CVE-2017-6983, CVE-2017-6991)

  • A memory corruption issue exists in the NVIDIA graphics drivers that allows a local attacker to execute arbitrary code with kernel-level privileges.
    (CVE-2017-6985)

  • A memory corruption issue exists in the iBooks component that allows an unauthenticated, remote attacker to escape an application’s sandbox. (CVE-2017-6986)

  • A certificate validation flaw exists in EAP-TLS within 802.1X authentication when a certificate has changed.
    An unauthenticated, adjacent attacker can exploit this, via a malicious network with 802.1X authentication, to capture user network credentials. (CVE-2017-6988)

  • An information disclosure vulnerability exists in HFS component due to improper sanitization of user-supplied input. A local attacker can exploit this to read the contents of restricted memory. (CVE-2017-6990)

  • Multiple type confusion flaws exist in SQLite due to improper validation of user-supplied input to ‘snippet’, ‘offsets’, and ‘matchinfo’. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website, to execute arbitrary code. (CVE-2017-7000, CVE-2017-7001, CVE-2017-7002)

  • A denial of service vulnerability exists in the CoreText component due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to crash an application. (CVE-2017-7003)

  • A race condition exists when performing userspace entitlement checks. A local attacker can exploit this to bypass restrictions and send privileged XPC messages without entitlements. (CVE-2017-7004)
