SUSE SLES11 Security Update : dosfstools (SUSE-SU-2016:2146-1)

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


Synopsis :

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

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).

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.
