VDR: Arbitrary file overwriting issue — GLSA 200501-42

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

Affected Packages

media-video/vdr on all architectures
Affected versions < 1.2.6-r1
Unaffected versions >= 1.2.6-r1

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.

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"
