Synopsis
========

VDR insecurely accesses files with elevated privileges, which may
result in the overwriting of arbitrary files.

Background
==========

Video Disk Recorder (VDR) is a Linux-based digital video recorder. The
VDR program handles the On Screen Menu system that offers complete
control over channel settings, timers and recordings.

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

    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  media-video/vdr     < 1.2.6-r1                        >= 1.2.6-r1

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

Javier Fernandez-Sanguino Pena from the Debian Security Audit Team
discovered that VDR accesses user-controlled files insecurely.

Impact
======

A local attacker could create malicious links and invoke a VDR
recording that would overwrite arbitrary files on the system.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All VDR users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/vdr-1.2.6-r1"
