Wolfram Kleff reported [1] that fetchmail would segfault when receiving emails with large "To:" headers. This was due to a buffer overflow in the header parser and it could be exploited remotely. SOLUTION It is recommended that all fetchmail users upgrade this package as soon as possible. IMPORTANT: it is necessary to manually restart the fetchmail daemon after installing the update!
