Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.4, macOS Mojave 10.14.6, tvOS 12.4, watchOS 5.3, Safari 12.1.2, iTunes for Windows 12.9.6, iCloud for Windows 7.13, iCloud for Windows 10.6. Processing maliciously crafted web content may lead to arbitrary code execution.

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 12.1.2 It is, therefore, affected by multiple vulnerabilities in the following components :

  - Safari
  - WebKit

According to its version, the iCloud application installed on the remote Windows host is 7.x prior to 7.13 or 10.x prior to 10.6. It is, therefore, affected by multiple vulnerabilities:

  - Multiple arbitrary code execution vulnerabilities exist with in the WebKit due to improper handling of maliciously     crafted content. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (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)

  - A cross-site scripting (XSS) vulnerability exists with in the WebKit due to improper handling synchronous page loads.
    An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to     execute arbitrary script code in a user's browser session. (CVE-2019-8649)

  - A cross-site scripting (XSS) vulnerability exists with in the WebKit due to improper validation of user-supplied     input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to     click a specially crafted URL, to execute arbitrary script code in a user's browser session. (CVE-2019-8658)

  - A cross-site scripting (XSS) vulnerability exists with in the WebKit due to improper handling of document loads. An     unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute     arbitrary script code in a user's browser session. (CVE-2019-8690)

  - An information disclosure vulnerability exists in the included libxslt library due to improper input validation. An     unauthenticated, remote attacker can exploit this, to disclose potentially sensitive information. (CVE-2019-13118)

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 :

  - 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)
