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"
