**Name of the Vulnerable Software and Affected Versions** AMD processors (affected versions not specified) **Description** A potential power side-channel issue in some AMD processors may allow an authenticated attacker to use the power reporting functionality to monitor a program’s execution inside an AMD SEV VM, potentially resulting in a leak of sensitive information. **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** AMD CPUs (affected versions not specified) **Description** The issue is related to the implementation of the SEV-SNP (Secure Nested Paging) protective mechanism for virtual machines running on servers with AMD processors, which is associated with data encryption errors. An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on AMD CPUs by monitoring ciphertext values over time. **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** AMD EPYC Processors (affected versions not specified) **Description** The issue is related to an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP) of AMD EPYC Processors. A local authenticated attacker could potentially exploit this vulnerability, leading to the leaking of guest data by a malicious hypervisor. **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: iOS versions prior to 11 macOS versions prior to 10.13 tvOS versions prior to 11 watchOS versions prior to 4 Description: The issue involves the Kernel component and allows attackers to obtain sensitive network-activity information about arbitrary apps via a crafted app. Recommendations: For iOS versions prior to 11, update to version 11 or later. For macOS versions prior to 10.13, update to version 10.13 or later. For tvOS versions prior to 11, update to version 11 or later. For watchOS versions prior to 4, update to version 4 or later.

Name of the Vulnerable Software and Affected Versions: iOS versions prior to 11 Description: An issue in certain Apple products involves the `Sandbox Profiles` component, allowing attackers to determine whether arbitrary files exist via a crafted app. Recommendations: For iOS versions prior to 11, update to a version 11 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** iOS versions prior to 11.1 macOS versions prior to 10.13.1 tvOS versions prior to 11.1 watchOS versions prior to 4.1 **Description** The issue involves the Kernel component and allows attackers to monitor arbitrary apps via a crafted app that accesses process information at a high rate. **Recommendations** For iOS versions prior to 11.1, update to version 11.1 or later. For macOS versions prior to 10.13.1, update to version 10.13.1 or later. For tvOS versions prior to 11.1, update to version 11.1 or later. For watchOS versions prior to 4.1, update to version 4.1 or later.
