Exim < 4.90.1 Remote Code Execution
High Nessus Network Monitor Plugin ID 700223
Synopsis
The remote mail server is vulnerable to a remote command execution attack.
Description
The remote host is running Exim, a message transfer agent.
Versions of Exim earlier than 4.90.1 are affected by an overflow condition in an unspecified utility function that is triggered as certain input is not properly validated when parsing messages. This may allow a remote attacker to cause a buffer overflow and potentially execute arbitrary code.
Solution
Upgrade to Exim 4.90.1 or later.
