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

medium Nessus Plugin ID 93335

Language:

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.

Solution

Update the affected dosfstools packages.
