    GENTOO LINUX SECURITY ANNOUNCEMENT
    - - --------------------------------------------------------------------

    PACKAGE        :gv
    SUMMARY        :Execution of Arbitrary Shell Commands
    DATE           :2002-10-03 10:00 UTC

    - - --------------------------------------------------------------------

    OVERVIEW

    GV can be tricked into executing arbitary shell commands.

    DETAIL

    When GV detects that the document is either a PDF file or a
    GZip compressed file, it executes some commands with the help
    of the system() function. Unfortunately, these commands
    contain the filename, which can be considered as untrusted user
    input. It is then possible to distribute a file (with a meticulously
    choosed filename, that can even seems innocent) that causes execution of
    arbitrary shell commands when it is read with GV.

    http://www.epita.fr/~bevand_m/asa/asa-0000

    SOLUTION

    It is recommended that all Gentoo Linux users who are running
    app-text/gv-3.58-r1 and earlier update their systems
    as follows:

    emerge rsync
    emerge gv
    emerge clean
