polkit - Temporary auth Hijacking via PID Reuse and Non-atomic Fork

/ When a non-root user attempts to e.g. control systemd units in the system instance from an active session over DBus, the access is gated by a polkit policy that requires "authadminkeep" auth. This results in an auth prompt being shown to the user, asking the user to confirm the action by enteri...

guava: Unbounded memory allocation in AtomicDoubleArray and CompoundOrdering classes allow remote attackers to cause a denial of service

A vulnerability was found in Guava where the AtomicDoubleArray and CompoundOrdering classes were found to allocate memory based on size fields sent by the client without validation. A crafted message could cause the server to consume all available memory or crash leading to a denial of service...

Using MITRE ATT&CK When Researching Attacker Behavior in a Post-Compromise World

MITRE ATT&CK is arguably one of the best assets available to security professionals who want to dive into the intricacies of detecting and preventing adversary behaviors. Why is that? It’s a great knowledge base of known adversarial behaviors overlayed with attacker TTPs and their state in the...
