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

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.
Javier Fernandez-Sanguino Pena from the Debian Security Audit Team discovered that VDR accesses user-controlled files insecurely.
A local attacker could create malicious links and invoke a VDR recording that would overwrite arbitrary files on the system.
There is no known workaround at this time.
All VDR users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-video/vdr-1.2.6-r1"
