An update that solves two vulnerabilities can now be installed.
Description:
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).
