On Unix platforms, when listing directory contents using `File.ReadDir` or `File.Readdir`, the returned `FileInfo` could reference a file outside the root directory in which the file was opened. This allows reading metadata from arbitrary locations on the filesystem using `lstat` without permitting file reading or writing outside the root. The issue impacts stdlib in 27 Lambda base images.

The issue is related to a use-after-free problem, which can cause a crash or potentially allow code execution during GPG signature verification. This is due to improper memory management, where memory passed to C may be freed before it is used, leading to crashes or possible code execution.

The issue allows arbitrary files on the system to be read due to a polkit policy in gnome-system-log.

The issue is related to information disclosure when the user's home directory is moved.

Name of the Vulnerable Software and Affected Versions: containers/image library used by Podman, Buildah, and Skopeo in Red Hat Enterprise Linux version 8 CRI-O in OpenShift Container Platform Description: The issue concerns the containers/image library, which does not enforce TLS connections to the container registry authorization service. This allows an attacker to launch a Man-in-the-Middle (MiTM) attack, potentially stealing login credentials or bearer tokens. The HTTP client used to connect to the container registry authorization service explicitly disables TLS verification, making it vulnerable to such attacks. Recommendations: For Red Hat Enterprise Linux version 8, update the containers/image library to a version that enforces TLS connections. For OpenShift Container Platform, update CRI-O to a version that enforces TLS connections. As a temporary workaround, consider restricting access to the container registry authorization service to minimize the risk of exploitation.

The issue allows local users to write to arbitrary files owned by the current user.

The issue allows local users to change the system timezone via a crafted D-Bus call due to the default configuration in mate-settings-daemon.

The issue is related to multiple vulnerabilities in various packages of the Automatic Bug Reporting Tool (ABRT) and libreport. These vulnerabilities can be exploited locally, potentially leading to a breach of confidentiality, integrity, and availability of protected information. According to the information provided, the exploitation can be carried out by modifying the PYTHONPATH environment variable to reference a malicious Python module, allowing local users to load and execute arbitrary Python modules.
