Synopsis
========

A stack-based buffer overflow vulnerability has been found in udisks,
allowing a local attacker to possibly execute arbitrary code or cause
Denial of Service.

Background
==========

udisks is an abstraction for enumerating block devices and performing
operations on them.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  sys-fs/udisks                < 2.1.3                   *>= 1.0.5 
                                                             >= 2.1.3 

Description
===========

A stack-based buffer overflow can be triggered when udisks is given a
long path name as a mount point.

Impact
======

A local attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All udisks 1.0 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-fs/udisks-1.0.5:0"

All udisks 2.0 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-fs/udisks-2.1.3"
