The OPC UA Legacy Java Stack before 6f176f2 enables an attacker to block OPC UA server applications via uncontrolled resource consumption so that they can no longer serve client applications.

Weak authentication in Microsoft Office SharePoint allows an unauthorized attacker to bypass a security feature over a network.

A remote unauthenticated attacker can send specially crafted TFTP requests to a Windows Server system running the Windows Deployment Services (WDS) role. Under specific timing conditions involving asynchronous file operations, the service may access memory that has already been released, which can result in remote code execution in the context of the WDS service. The attack is network-based, requires no authentication or user interaction, and targets systems exposing the WDS TFTP service.
