Fedora 26: Security Update for Tnef - Critical Integer Underflow

This application provides a way to unpack Microsoft MS-TNEF MIME attachments.

It operates like tar in order to unpack files of type "application/ms-tnef",

which may have been placed into the MS-TNEF attachment instead of being

attached separately.

Such files may have attachment names similar to WINMAIL.DAT
