Synopsis :

The remote Gentoo host is missing one or more security-related

handling Exif data.

Impact :

An attacker could entice a user to process a file with specially
crafted Exif extensions with an application making use of libexif,
which will trigger the integer overflow and potentially execute
arbitrary code or crash the application.
