Gentoo Linux Security Advisory

Title: VDR: Arbitrary file overwriting issue (GLSA 200501-42)
Severity: normal
Exploitable: local
Date: January 30, 2005
Bug(s): #78230
ID: 200501-42

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: media-video/vdr
Vulnerable: < 1.2.6-r1
Unaffected: >= 1.2.6-r1
Architectures: All supported architectures


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