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"
