(Berkeley MPEG Tools: Multiple insecure temporary files)

    Mike Frysinger of the Gentoo Security Team discovered that
    mpeg_encode and the conversion utilities were creating temporary files
    with predictable or fixed filenames. The 'test' make target of the MPEG
    Tools also relied on several temporary files created insecurely.
  
Impact :

    A local attacker could create symbolic links in the temporary
    files directory, pointing to a valid file somewhere on the filesystem.
    When the utilities are executed (or 'make test' is run), this would
    result in the file being overwritten with the rights of the user
    running the command.
  
Workaround :

    There is no known workaround at this time."
