Fedora 25 Moderate Update: LibTiff Buffer Overflow Issues Fixed

The libtiff package contains a library of functions for manipulating

TIFF (Tagged Image File Format) image format files. TIFF is a widely

used file format for bitmapped images. TIFF files usually end in the

.tif extension and they are often quite large.

The libtiff package should be installed if you need to manipulate TIFF

format image files.
