SUSE SLED12 / SLES12 Security Update : dosfstools (SUSE-SU-2016:2145-1)

Low Nessus Plugin ID 93304


The remote SUSE host is missing one or more security updates.


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).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
