    <p>
    The Linux Security Auditing Tool (LSAT) is a post install security
    auditor which checks many system configurations and local network
    settings on the system for common security or configuration errors and
    for packages that are not needed.

    <p>
    LSAT insecurely writes in /tmp with a predictable filename.
    </p>
  </description>
  <impact type="low">
    <p>
    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.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All lsat users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-admin/lsat-0.9.5"</code>
