FreeBSD : fetchmail -- NULL pointer dereference in multidrop mode with headerless email (f7eb0b23-7099-11da-a15c-0060084a00e5)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

The fetchmail team reports :

Fetchmail contains a bug that causes an application crash when
fetchmail is configured for multidrop mode and the upstream mail
server sends a message without headers. As fetchmail does not record
this message as 'previously fetched', it will crash with the same
message if it is re-executed, so it cannot make progress. A malicious
or broken-into upstream server could thus cause a denial of service in
fetchmail clients.
