**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 133.0.6943.53 Microsoft Edge (affected versions not specified) **Description** The issue is related to a use after free in Skia, allowing a remote attacker to potentially exploit heap corruption via a crafted HTML page. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited. Technical details include concurrent access to `SkFontationsScalerContext`, which may lead to a race condition and use-after-free. The `generateYScalePathForGlyphId()` function can be called from a COLRv1 SkDrawable. **Recommendations** For Google Chrome versions prior to 133.0.6943.53, update to version 133.0.6943.53 or later to resolve the issue. For Microsoft Edge, at the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to potentially vulnerable components until a patch is available.

**Name of the Vulnerable Software and Affected Versions** watchOS versions prior to 10 iOS versions prior to 17 iPadOS versions prior to 17 tvOS versions prior to 17 macOS versions prior to Sonoma 14 Safari versions prior to 17 **Description** The issue is related to a use-after-free problem in the WebKit component, which can be exploited by a remote attacker to execute arbitrary code using a specially crafted link. Processing web content may lead to arbitrary code execution. The estimated number of potentially affected devices worldwide is not specified. **Recommendations** For watchOS versions prior to 10, update to watchOS 10 or later. For iOS versions prior to 17, update to iOS 17 or later. For iPadOS versions prior to 17, update to iPadOS 17 or later. For tvOS versions prior to 17, update to tvOS 17 or later. For macOS versions prior to Sonoma 14, update to macOS Sonoma 14 or later. For Safari versions prior to 17, update to Safari 17 or later.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 116.0.5845.110 **Description** The issue is related to an out of bounds memory access in the CSS component of Google Chrome, allowing a remote attacker to perform an out of bounds memory read via a crafted HTML page. This could potentially impact the confidentiality, integrity, and availability of protected information. **Recommendations** For versions prior to 116.0.5845.110, update to version 116.0.5845.110 or later to resolve the issue.

Improved memory handling has been implemented to address this issue. **Recommendations** For versions prior to watchOS 9.3, update to watchOS 9.3 or later. For versions prior to tvOS 16.3, update to tvOS 16.3 or later. For versions prior to macOS Ventura 13.2, update to macOS Ventura 13.2 or later. For versions prior to iOS 16.3, update to iOS 16.3 or later. For versions prior to iPadOS 16.3, update to iPadOS 16.3 or later.

**Name of the Vulnerable Software and Affected Versions** Safari versions prior to 16.1 macOS versions prior to Ventura 13 iOS versions prior to 16.1 iPadOS versions prior to 16 **Description** A use after free issue was addressed with improved memory management. Processing maliciously crafted web content may lead to arbitrary code execution. The issue is related to the use of memory after it has been freed when handling web content, which can be exploited by a remote attacker to execute arbitrary code. **Recommendations** For Safari versions prior to 16.1, update to Safari 16.1 or later. For macOS versions prior to Ventura 13, update to macOS Ventura 13 or later. For iOS versions prior to 16.1, update to iOS 16.1 or later. For iPadOS versions prior to 16, update to iPadOS 16 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 74.0.1 Firefox ESR versions prior to 68.6.1 Thunderbird versions prior to 68.7.0 **Description** The issue is related to a use-after-free flaw in the nsDocShell destructor, which can be triggered under certain conditions. This can lead to a race condition, causing the use-after-free. There have been targeted attacks in the wild exploiting this flaw. The exploitation of this issue may allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service. **Recommendations** For Firefox versions prior to 74.0.1, update to version 74.0.1 or later. For Firefox ESR versions prior to 68.6.1, update to version 68.6.1 or later. For Thunderbird versions prior to 68.7.0, update to version 68.7.0 or later.
