http://security.gentoo.org/

Severity:	normal
Title:	VDR: Arbitrary file overwriting issue
Date:	01/30/2005
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
media-video/vdr	< 1.2.6-r1	>= 1.2.6-r1	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:

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