openSUSE Security Update : dosfstools (openSUSE-2016-1045)

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

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).

This non-security issue was fixed :

- bsc#912607: Attempt to rename root dir in fsck due to
uninitialized fields. This update was imported from the
SUSE:SLE-12:Update update project.
