Fetchmail Verbose Mode Large Log Messages Remote Denial of Service Vulnerability

Fetchmail is prone to a denial-of-service vulnerability because the application fails to handle exceptional conditions.

An attacker can exploit this issue to crash the affected application, denying service to legitimate users. Given the nature of the issue, remote code execution may also be possible, but this has not been confirmed.

Versions prior to Fetchmail 6.3.9 are vulnerable.
