    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"
