**Name of the Vulnerable Software and Affected Versions** tvOS versions prior to 16.1 iOS versions prior to 15.7.1 and prior to 16.1 iPadOS versions prior to 15.7.1 and prior to 16.1 macOS Ventura versions prior to 13 watchOS versions prior to 9.1 Safari versions prior to 16.1 **Description** A correctness issue in the JIT was addressed with improved checks. Processing maliciously crafted web content may disclose internal states of the app. The issue is related to errors in managing the state of WebKitGTK and WPE WebKit modules, which can allow a remote attacker to access confidential data. **Recommendations** For tvOS versions prior to 16.1, update to tvOS 16.1. For iOS versions prior to 15.7.1, update to iOS 15.7.1 or later. For iOS versions prior to 16.1, update to iOS 16.1. For iPadOS versions prior to 15.7.1, update to iPadOS 15.7.1 or later. For iPadOS versions prior to 16.1, update to iPadOS 16.1. For macOS Ventura versions prior to 13, update to macOS Ventura 13. For watchOS versions prior to 9.1, update to watchOS 9.1. For Safari versions prior to 16.1, update to Safari 16.1.

**Name of the Vulnerable Software and Affected Versions** Foxit Reader version 10.1.1.37576 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of XFA forms due to the lack of proper validation of user-supplied data. This can result in a write past the end of an allocated data structure, allowing an attacker to execute code in the context of the current process. **Recommendations** For Foxit Reader version 10.1.1.37576, consider disabling the handling of XFA forms as a temporary workaround until a patch is available. Restrict access to potentially malicious pages or files to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Foxit Reader version 10.1.1.37576 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of XFA Forms due to the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this to execute code in the context of the current process. **Recommendations** For Foxit Reader version 10.1.1.37576, consider disabling the handling of XFA Forms as a temporary workaround until a patch is available. Restrict access to malicious pages and files to minimize the risk of exploitation. 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** Foxit Reader version 10.1.1.37576 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of the Decimal element, specifically through a crafted `leadDigits` value that can trigger an overflow of a fixed-length heap-based buffer. This can be leveraged to execute arbitrary code in the context of the current process. **Recommendations** For Foxit Reader version 10.1.1.37576, consider disabling the handling of Decimal elements or restricting access to potentially malicious files and web pages until a patch is available. Avoid using crafted `leadDigits` values in Decimal elements to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
