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

High Nessus Plugin ID 21541


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


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.


Update the affected package.
