**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 12.4 **Description** The issue is related to a sandboxed process that may be able to circumvent sandbox restrictions. This is due to insufficient access control when handling XPC messages in the LaunchServices service of Mac OS. Exploitation of this issue may allow an attacker to bypass security restrictions and escalate their privileges. The issue was addressed with improved environment sanitization. **Recommendations** For versions prior to 12.4, update to macOS Monterey 12.4 to fix the issue. As a temporary workaround, consider restricting access to the LaunchServices to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 12.0.1 macOS Big Sur versions prior to 11.6.6 **Description** A logic issue was addressed with improved state management. This issue allows a sandboxed process to potentially circumvent sandbox restrictions. The vulnerability was discovered while studying methods of launching and detecting malicious macros in Office documents on macOS. Researchers found that using Launch Services to run a command with a specific prefix allows escaping the app sandbox in macOS. **Recommendations** For macOS versions prior to 12.0.1, update to macOS Monterey 12.0.1 or later to fix the issue. For macOS Big Sur versions prior to 11.6.6, update to macOS Big Sur 11.6.6 or later to fix the issue. As a temporary workaround, consider restricting the use of Launch Services and the `open` command with the `--stdin` option to minimize the risk of exploitation. Avoid using malicious macros in Office documents until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** Windows Installer (affected versions not specified) **Description** The issue is related to errors in the representation of information by the user interface of the Windows Installer component in Microsoft Windows operating systems. This can allow an attacker to conduct spoofing attacks. **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** Apple iOS versions prior to 14.6 Apple iPadOS versions prior to 14.6 Apple tvOS versions prior to 14.6 Apple watchOS versions prior to 7.5 Apple macOS versions prior to 11.4 Apple macOS Catalina versions prior to Security Update 2021-004 Apple macOS Mojave versions prior to Security Update 2021-005 **Description** The issue is related to errors in security settings of the Launch Services in iOS, iPadOS, tvOS, watchOS, and macOS operating systems. A malicious application may be able to break out of its sandbox due to improved environment sanitization not being in place. This could allow an attacker to escape the App Sandbox and bypass privacy protections. **Recommendations** For Apple iOS versions prior to 14.6, update to iOS 14.6 or later. For Apple iPadOS versions prior to 14.6, update to iPadOS 14.6 or later. For Apple tvOS versions prior to 14.6, update to tvOS 14.6 or later. For Apple watchOS versions prior to 7.5, update to watchOS 7.5 or later. For Apple macOS versions prior to 11.4, update to macOS Big Sur 11.4 or later. For Apple macOS Catalina versions prior to Security Update 2021-004, apply Security Update 2021-004 or later. For Apple macOS Mojave versions prior to Security Update 2021-005, apply Security Update 2021-005 or later.

Name of the Vulnerable Software and Affected Versions: Windows Installer (affected versions not specified) Description: The issue is related to errors in the representation of information by the user interface of the Windows Installer component in Microsoft Windows operating systems. This can allow an attacker to conduct spoofing attacks. The vulnerability may be exploited to affect the system. 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** Electronic Arts Origin versions prior to 10.5.39 **Description** An issue was discovered due to improper sanitization of the `origin://` and `origin2://` URI schemes, allowing injection of additional arguments into the Origin process. This can lead to code execution by loading a backdoored Qt plugin remotely via the `platformpluginpath` argument supplied with a Windows network share. **Recommendations** For versions prior to 10.5.39, update to version 10.5.39 or later to resolve the issue. As a temporary workaround, consider restricting access to the `origin://` and `origin2://` URI schemes to minimize the risk of exploitation. Avoid using the `platformpluginpath` argument in the affected URI schemes until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** Adobe Acrobat versions prior to 2019.010.20101 Adobe Acrobat Reader versions prior to 2019.010.20101 Adobe Acrobat 2019 versions prior to 2019.010.20101 Adobe Acrobat Reader 2019 versions prior to 2019.010.20101 Adobe Acrobat 2017 versions prior to 2017.011.30141 Adobe Acrobat Reader 2017 versions prior to 2017.011.30141 Adobe Acrobat 2015 versions prior to 2015.006.30496 Adobe Acrobat Reader 2015 versions prior to 2015.006.30496 **Description** The issue is related to an out-of-bounds read operation in memory, which can be exploited by a remote attacker to gain unauthorized access to protected information. This can lead to information disclosure. **Recommendations** For Adobe Acrobat and Reader 2019, update to version 2019.010.20101 or later. For Adobe Acrobat and Reader 2017, update to version 2017.011.30141 or later. For Adobe Acrobat and Reader 2015, update to version 2015.006.30496 or later. As a temporary workaround, consider restricting access to sensitive information until a patch is applied.
