(LSAT: Insecure temporary file creation)

    LSAT insecurely writes in /tmp with a predictable filename.
  
Impact :

    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    the LSAT script is executed, this would result in the file being
    overwritten with the rights of the user running the software, which
    could be the root user.
  
Workaround :

    There is no known workaround at this time."
