The remote host is running Mac OS X 10.12.6 or Mac OS X 10.13.6 and is missing a security update. It is, therefore, affected by multiple vulnerabilities :
An application may be able to read restricted memory (CVE-2019-8691, CVE-2019-8692, CVE-2019-8693)
Extracting a zip file containing a symbolic link to an endpoint in an NFS mount that is attacker controlled may bypass Gatekeeper (CVE-2019-8656)
A remote attacker may be able to cause arbitrary code execution (CVE-2019-8648, CVE-2018-19860, CVE-2019-8661)
A remote attacker may be able to leak memory (CVE-2019-8646, CVE-2019-8663)
A remote attacker may be able to cause unexpected application termination or arbitrary code execution ( CVE-2019-8641, CVE-2019-8660)
An application may be able to execute arbitrary code with system privileges (CVE-2019-8695, CVE-2019-8697)
An issue existed in Samba that may allow attackers to perform unauthorized actions by intercepting communications between services (CVE-2018-16860)
An application may be able to execute arbitrary code with kernel privileges (CVE-2019-8694)
A remote attacker may be able to view sensitive information (CVE-2019-13118)
An attacker may be able to trigger a use-after-free in an application deserializing an untrusted NSDictionary (CVE-2019-8662)
Visiting a malicious website may lead to address bar spoofing (CVE-2019-8670)
The encryption status of a Time Machine backup may be incorrect (CVE-2019-8667)
Parsing a maliciously crafted office document may lead to an unexpected application termination or arbitrary code execution (CVE-2019-8657)
Processing maliciously crafted web content may lead to universal cross site scripting (CVE-2019-8649, CVE-2019-8658, CVE-2019-8690)
Processing maliciously crafted web content may lead to arbitrary code execution (CVE-2019-8644, CVE-2019-8666, CVE-2019-8669, CVE-2019-8671, CVE-2019-8672, CVE-2019-8673, CVE-2019-8676, CVE-2019-8677, CVE-2019-8678, CVE-2019-8679, CVE-2019-8680, CVE-2019-8681, CVE-2019-8683, CVE-2019-8684, CVE-2019-8685, CVE-2019-8686, CVE-2019-8687, CVE-2019-8688, CVE-2019-8689)
