Summary
Security update for dosfstools

Notes

Title of the patch
Security update for dosfstools
Description of the patch
dosfstools was updated to fix two security issues. These security issues were fixed: - CVE-2015-8872: The set_fat function in fat.c in dosfstools might have allowed attackers to corrupt a FAT12 filesystem or cause a denial of service (invalid memory read and crash) by writing an odd number of clusters to the third to last entry on a FAT12 filesystem, which triggers an 'off-by-two error (bsc#980364). - CVE-2016-4804: The read_boot function in boot.c in dosfstools allowed attackers to cause a denial of service (crash) via a crafted filesystem, which triggers a heap-based buffer overflow in the (1) read_fat function or an out-of-bounds heap read in (2) get_fat function (bsc#980377).
