**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 10.13.5 **Description** The issue involves the `IOFireWireAVC` component and allows attackers to execute arbitrary code in a privileged context via a crafted app that leverages a race condition. This is related to synchronization errors when using a shared resource, which can be exploited by an attacker to execute arbitrary code with kernel privileges using a specially crafted application. **Recommendations** For macOS versions prior to 10.13.5, update to version 10.13.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the `IOFireWireAVC` component to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 10.13 **Description** The issue involves the IOFireWireFamily component and allows attackers to bypass intended memory-read restrictions via a crafted app. **Recommendations** For macOS versions prior to 10.13, update to version 10.13 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 10.12.4 **Description** The issue involves the `IOFireWireAVC` component and allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors. It is caused by a buffer overflow in memory, which can be exploited by a local attacker to elevate privileges or cause a denial of service. **Recommendations** For macOS versions prior to 10.12.4, update to version 10.12.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the `IOFireWireAVC` component to minimize the risk of exploitation.
