A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 13.2 and iPadOS 13.2, macOS Catalina 10.15.1, iTunes for Windows 12.10.2, iCloud for Windows 11.0, iCloud for Windows 7.15. An application may be able to execute arbitrary code with system privileges.

According to its version, the iCloud application installed on the remote Windows host is 10.x prior to 10.8. It is, therefore, affected by multiple vulnerabilities:

  - Multiple arbitrary code execution vulnerabilities exist with in the WebKit due to multiple memory     corruption issues. An unauthenticated, remote attacker can exploit this to execute arbitrary code.     (CVE-2019-8710, CVE-2019-8766, CVE-2019-8782, CVE-2019-8783, CVE-2019-8784, CVE-2019-8811, CVE-2019-8814,     CVE-2019-8816, CVE-2019-8819, CVE-2019-8820, CVE-2019-8821, CVE-2019-8822, CVE-2019-8823)

  - Multiple issues exist with in the Libxslt due to multiple memory corruption issue. (CVE-2019-8750)

  - An cross site scripting vulnerability exist with in the WebKit due to logic issue. An unauthenticated,     remote attacker can exploit this by processing maliciously crafted web content may lead to universal     cross site scripting. (CVE-2019-8813)

  - An arbitrary code execution vulnerability exist with in the WebKit due to multiple memory corruption     issue. An unauthenticated, remote attacker can exploit this by processing maliciously crafted web     content may lead to arbitrary code execution. (CVE-2019-8815)

According to its version, the iCloud application installed on the remote Windows host is 7.x prior to 7.15. It is, therefore, affected by multiple vulnerabilities:

  - Multiple arbitrary code execution vulnerabilities exist with in the WebKit due to multiple memory     corruption issues. An unauthenticated, remote attacker can exploit this to execute arbitrary code.     (CVE-2019-8783, CVE-2019-8784, CVE-2019-8811, CVE-2019-8814, CVE-2019-8815, CVE-2019-8816, CVE-2019-8819,     CVE-2019-8820, CVE-2019-8821, CVE-2019-8822, CVE-2019-8823)

The version of Apple iTunes installed on the remote Windows host is prior to 12.10.2. It is, therefore, affected by multiple vulnerabilities as referenced in the HT210726 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is running a version of macOS or Mac OS X that is 10.15.x prior to 10.15.1, 10.14.x prior to 10.14.6 security update 2019-001, 10.13.x prior to 10.13.6 security update 2019-006. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the accounts component due to improper input validation. A remote     attacker can exploit this, to disclose memory contents. (CVE-2019-8787)

  - A security bypass vulnerability exists in the App Store component due to an improper state management     implementation. A local attacker can exploit this, to login to the account of a previously logged in user     without valid credentials. (CVE-2019-8803)

  - An out-of-bounds read error exists in the IOGraphics component due to improper bounds checking. A local     attacker can exploit this, to cause unexpected system termination or to read kernel memory.     (CVE-2019-8759)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

The version of Apple iOS running on the mobile device is prior to 13.2. It is, therefore, affected by multiple vulnerabilities.
  - A memory leak vulnerablity exists in the iOS Accounts, a remote attacker can exploit this using specially     crafted input. (CVE-2019-8787)

  - An authentication vulnerability exists in the iOS App store, a local attacker may be able to login to the     account of a previously logged in user without valid credentials. (CVE-2019-8803)

  - Associated Domains vulnerable to data exfiltration. The attacker can exploit this issue by passing improper     URL. An issue existed in the parsing of URLs. (CVE-2019-8788)

  - A memory corruption issue exist in iOS Audio and AVEVideoEncoder. An application may be able to execute     arbitrary code with system privileges. (CVE-2019-8785, CVE-2019-8797, CVE-2019-8795)

  - A validation issue existed in the handling of symlinks in iOS Books. Parsing a maliciously crafted iBooks file     may lead to disclosure of user information. (CVE-2019-8789)

  - An inconsistent user interface issue exist in the iOS Contacts, processing a maliciously contact may lead to     UI spoofing. (CVE-2017-7152)

  - A memory corruption issue exists in the iOS File System Events, Graphics Driver, Kernel. An application may     be able to execute arbitrary code with system privileges. (CVE-2019-8798, CVE-2019-8784, CVE-2019-8786)

  - An input validation exists in the iOS Kernel. An application may be able to read restricted memory.
    (CVE-2019-8794)

  - An inconsistency in Wi-Fi network configuration in iOS Setup Assistant is vulnerable. An attacker in physical     proximity may be able to force a user onto a malicious Wi-Fi network during device setup. (CVE-2019-8804)

  - A iOS Screen Recording is vulnerable, a local user may be able to record the screen without a visible screen     recording indicator. (CVE-2019-8793)

  - A cross-site scripting (XSS) vulnerability exists in iOS WebKit due to improper validation of user-supplied     input before returning it to users. Processing maliciously crafted web content may lead to universal cross site     scripting. (CVE-2019-8813)

  - An arbitrary code execution vulnerability exists in iOS WebKit and WebKit Processing Model. Multiple memory     corruption vulnerabilities while processing maliciously crafted web content may lead to arbitrary code execution.
   (CVE-2019-8783, CVE-2019-8808, CVE-2019-8811, CVE-2019-8812, CVE-2019-8814, CVE-2019-8816, CVE-2019-8819,    CVE-2019-8820, CVE-2019-8821, CVE-2019-8822, CVE-2019-8823, CVE-2019-8815, CVE-2019-8782)
