Description

Fetchmail contains a bug where when running in multidrop mode, a malicious mail server can crash the client by sending a message without headers.

This update fixes the issue.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
