Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 5.0 and .NET Core 3.1. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A denial of service vulnerability exists in .NET 5.0, .NET Core 3.1 and .NET Core 2.1 where .NET (Core) server applications providing WebSocket endpoints could be tricked into endlessly looping while trying to read a single WebSocket frame. ### Patches * If you're using .NET 5.0, you should download and install Runtime 5.0.9 or SDK 5.0.206 (for Visual Studio 2019 v16.8) or SDK 5.0.303 (for Visual Studio 2019 V16.10) from https://dotnet.microsoft.com/download/dotnet-core/5.0. * If you're using .NET Core 3.1, you should download and install Runtime 3.1.18 or SDK 3.1.118 (for Visual Studio 2019 v16.4) or 3.1.412 (for Visual Studio 2019 v16.7 or later) from https://dotnet.microsoft.com/download/dotnet-core/3.1. * If you're using .NET Core 2.1, ...

PRTG Network Monitor through 22.2.77.2204 does not prevent custom input for a device’s icon, which can be modified to insert arbitrary content into the style tag for that device. When the device page loads, the arbitrary Cascading Style Sheets (CSS) data is inserted into the style tag, loading malicious content. Due to PRTG Network Monitor preventing “characters, and from modern browsers disabling JavaScript support in style tags, this vulnerability could not be escalated into a Cross-Site Scripting vulnerability.

Azure CLI is the command-line interface for Microsoft Azure. In versions previous to 2.40.0, Azure CLI contains a vulnerability for potential code injection. Critical scenarios are where a hosting machine runs an Azure CLI command where parameter values have been provided by an external source. The vulnerability is only applicable when the Azure CLI command is run on a Windows machine and with any version of PowerShell and when the parameter value contains the `&` or `|` symbols. If any of these prerequisites are not met, this vulnerability is not applicable. Users should upgrade to version 2.40.0 or greater to receive a a mitigation for the vulnerability.

Trend Micro research finds most are over-confident about ability to withstand ransomware.

Cybersecurity researchers have disclosed details about a pair of vulnerabilities in Microsoft Windows, one of which could be exploited to result in a denial-of-service (DoS). The exploits, dubbed LogCrusher and OverLog by Varonis, take aim at the EventLog Remoting Protocol (MS-EVEN), which enables remote access to event logs. While the former allows "any domain user to remotely

Container and Kubernetes adoption brings the promise of faster application development and delivery at larger scales -- however, it also brings with it new security challenges. Protecting cloud-native applications can require significant changes in how organizations approach IT security. They need to apply controls earlier in the application development lifecycle, use existing infrastructure to apply and enforce these controls, keep up with increasingly rapid release schedules, and more.
