Serious code-execution vulnerability in Exim

The Devcore researchers said as many as 400,000 servers are at risk. Queries on the Shodan computer search engine identified a large number of servers that reported running vulnerable versions. The developers published a fix with version 4.90.1, which was released on February 10.

Any organization that uses Exim should ensure it’s using the latest version.
