Live microsoft announcement 2012




















Azure Spring Cloud will take steps to automatically protect customers and auto-restart any application with activated New Relic or AppDynamics Java Agents by Tuesday, December 21 st , to ensure the latest fixes take effect. Cosmos DB SDKs do not have dependency on Log4j 2 and allow customers to independently bring their own logging technologies. If customers independently decide to use Log4j 2 they should ensure to use Log4j 2. Cosmos DB Spark Connector utilizes underlying spark offering logging technologies.

While the industry is determining and mitigating overall exposure, attackers are probing all endpoints for vulnerabilities. Applying rigorous least privilege access policies to all resources in your environment is critical. If you use Azure Active Directory for single-sign on in your environment, we recommend you do the following with a special focus on applications you deploy or manage directly SaaS apps, including those deployed by Microsoft, must be secured by their vendors.

Note that log4j2 usage may be pre-auth for some of your applications, but these steps will help prevent post-authentication exploitation. Templates and examples for these policies are built in to facilitate deployment:. Minecraft customers running their own servers are encouraged to deploy the latest Minecraft server update to protect their users.

Note : If an application in the VM uses Log4j, it may be susceptible to this vulnerability. Please follow mitigation guidance published here. Microsoft security teams have put together the following guidance and resources to help customers understand these vulnerabilities and to help detect and hunt for exploits:. Added guidance for Java 7. Added guidance on Azure libraries for Java. Skip to content Published on: Dec 11, updated Dec Java 8 or newer: update Log4j to 2.

Apache Announcement: Log4j 1. These workarounds should not be considered a complete solution to resolve these vulnerabilities: For all releases of Log4j 2. Customers can do this by deleting the class from affected JAR files. In case the Log4j 2 vulnerable component cannot be updated, Log4j versions 2. Alternatively, customers using Log4j 2. An application restart will be required for these changes to take effect.

Analysis of the vulnerabilities The vulnerabilities allow remote code execution by an unauthenticated attacker to gain complete access to a target system.

CVE and CE exploit vectors and attack chain Mitigation Guidance for Microsoft Services After further analysis of our services and products, below are a few mitigation strategies given by various Microsoft services. Azure Application Gateway, Azure Front Door, and Azure WAF In our investigation so far, we have not found any evidence that these services are vulnerable however customer applications running behind these services might be vulnerable to this exploit.

Azure Databricks Your instance may be vulnerable if you have installed an affected version of Log4j or have installed services that transitively depend on an affected version. Azure Functions Customers are recommended to apply the latest Log4j security updates and re-deploy applications.

Action recommended For new clusters created using HDI 4. Log4j usage may originate from: Your application sources. Application Performance Monitoring tools activated for the application. Spring Boot Applications Spring Boot applications are only affected if they have switched the default logging framework to Log4j 2. For Example — set the system property log4j2. Microsoft Azure AD While the industry is determining and mitigating overall exposure, attackers are probing all endpoints for vulnerabilities.

Enable MFA for all access to these resources to prevent probing using accounts with compromised passwords. If you are using Azure AD Identity Protection, enable blocking on risky logins we recommend blocking on medium or higher. Monitor the risky sign in reports or use the risk workbook to track anomalous logins to your applications to help focus your investigations.

Some kind of Hulu partnership, perhaps, or a similar buy-in from Big Entertainment which would explain the location.

Connectivity with the Xbox , hopefully. Maybe it'll even run on something other than Windows 8, just to make things kind of interesting. But for this kind of hoopla, to paraphrase that great tech guru Dr. Evil, this tablet needs to be strapped to a shark that shoots frickin' lasers.
