**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.

**Name of the Vulnerable Software and Affected Versions** Huawei HiSuite versions prior to 4.0.4.204 ove (Out of China) Huawei HiSuite versions prior to 4.0.4.301 (China) **Description** The issue allows local users to gain SYSTEM privileges via a Trojan horse `SspiCli.dll` or `USERENV.dll` file or possibly other unspecified DLL files, due to a weak ACL for the HiSuite service directory. **Recommendations** For versions prior to 4.0.4.204 ove (Out of China), update to version 4.0.4.204 ove or later. For versions prior to 4.0.4.301 (China), update to version 4.0.4.301 or later.
