Exim < 4.76 dkim_exim_verify_finish Remote Format String Vulnerability
Medium Nessus Network Monitor Plugin ID 5911
The remote mail server is vulnerable to a command execution attack.
The remote host is running Exim, a message transfer agent. Versions of Exim earlier than 4.76 are potentially affected by a format string vulnerability in logging DKIM information from an inbound email. By sending a specially crafted message to the server, a remote attacker can leverage this vulnerability to execute arbitrary code on the server subject to the privileges of the user running the affected application.
