Detailed Explanation for this Vulnerability Test
The remote host is missing the patch for the advisory FEDORA-2005-1046 (libungif).

loading and saving GIF format image files. The libungif library can
load any GIF file, but it will save GIFs only in uncompressed format

compressed GIF files).
Install the libungif package if you need to manipulate GIF files. You
should also install the libungif-progs package.
