This is an update fixing off-by-2 error leading to corruption in FAT12 ( CVE-2015-8872) and heap-buffer-overflows in read_fat() and get_fat() functions (CVE-2016-4804).
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
