Processing maliciously crafted web content may lead to a cross-site scripting attack. **Recommendations** For iTunes versions prior to 12.11.3 for Windows, update to version 12.11.3 or later. For iCloud for Windows versions prior to 12.3, update to version 12.3 or later. For macOS Big Sur versions prior to 11.3, update to version 11.3 or later. For Safari versions prior to 14.1, update to version 14.1 or later. For watchOS versions prior to 7.4, update to version 7.4 or later. For tvOS versions prior to 14.5, update to version 14.5 or later. For iOS versions prior to 14.5, update to version 14.5 or later. For iPadOS versions prior to 14.5, update to version 14.5 or later.

Name of the Vulnerable Software and Affected Versions: macOS versions prior to 11.3 iOS versions prior to 14.5 iPadOS versions prior to 14.5 watchOS versions prior to 7.4 tvOS versions prior to 14.5 Description: The issue is related to a memory corruption problem due to a buffer overflow in the WebKitGTK module. This can be exploited by a remote attacker using a specially crafted malicious web page, potentially leading to arbitrary code execution. The problem was addressed with improved state management. Recommendations: For macOS versions prior to 11.3, update to macOS Big Sur 11.3 or later. For iOS versions prior to 14.5, update to iOS 14.5 or later. For iPadOS versions prior to 14.5, update to iPadOS 14.5 or later. For watchOS versions prior to 7.4, update to watchOS 7.4 or later. For tvOS versions prior to 14.5, update to tvOS 14.5 or later.

Name of the Vulnerable Software and Affected Versions: Safari versions prior to 14.0 Description: The issue is related to an out-of-bounds write problem in the WebKit component of the Apple Safari browser. It may allow a remote attacker to execute arbitrary code by processing maliciously crafted web content. Recommendations: For versions prior to 14.0, update to Safari 14.0 to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Microsoft Edge ChakraCore (affected versions not specified) **Description** The issue is related to errors in handling objects in memory by the ChakraCore scripting engine. This could allow a remote attacker to execute arbitrary code in the context of the current user, potentially gaining the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Microsoft Edge (affected versions not specified) **Description** The issue exists due to errors in handling objects in memory by the scripting engine. It may allow a remote attacker to execute arbitrary code using a specially crafted web page. The vulnerability could corrupt memory, enabling an attacker to gain the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** watchOS versions prior to 6.1 **Description** The issue arises from multiple memory corruption problems related to memory handling. Processing maliciously crafted web content may lead to arbitrary code execution, allowing attackers to execute arbitrary code. **Recommendations** For versions prior to 6.1, update to watchOS 6.1 to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Safari versions prior to 12.1 iOS versions prior to 12.2 tvOS versions prior to 12.2 watchOS versions prior to 5.2 iTunes versions prior to 12.9.4 for Windows iCloud for Windows versions prior to 7.11 **Description** The issue is related to insufficient input validation in the WebKit display module. Exploitation of this issue may allow a remote attacker to gain unauthorized access to protected information. Processing maliciously crafted web content may result in the disclosure of process memory. **Recommendations** For Safari versions prior to 12.1, update to Safari 12.1 or later. For iOS versions prior to 12.2, update to iOS 12.2 or later. For tvOS versions prior to 12.2, update to tvOS 12.2 or later. For watchOS versions prior to 5.2, update to watchOS 5.2 or later. For iTunes versions prior to 12.9.4 for Windows, update to iTunes 12.9.4 for Windows or later. For iCloud for Windows versions prior to 7.11, update to iCloud for Windows 7.11 or later.

**Name of the Vulnerable Software and Affected Versions** ChakraCore (affected versions not specified) **Description** An information disclosure issue exists due to improper memory handling by Chakra, potentially allowing an attacker to gain information that could further compromise a user's computer or data. To exploit this, an attacker must be aware of the memory address where an object was created. The issue is related to errors in handling internal data. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
