Default 21 Vulnerabilities in Exim mail server

From https://therecord.media/21nails-vuln...email-servers/

Quote:
The maintainers of the Exim email server software have released updates today to patch a collection of 21 vulnerabilities that can allow threat actors to take over servers using both local and remote attack vectors.

Known as 21Nails, the vulnerabilities were discovered by security firm Qualys.

The bugs impact Exim, a type of email server known as a mail transfer agent (MTA) that helps email traffic travel across the internet and reach its intended destinations.

While there are different MTA clients available, an April 2021 survey shows that Exim has a market share of nearly 60% among all MTA solutions, being widely adopted around the internet.

The 21Nails vulnerabilities, if left unpatched, could allow threat actors to take over these systems and then intercept or tamper with email communications passing through the Exim server.
