"The remote host is affected by the vulnerability described in GLSA-200411-13
(Portage, Gentoolkit: Temporary file vulnerabilities)

    dispatch-conf and qpkg use predictable filenames for temporary files.
  
Impact :

    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    an affected script is called, this would result in the file to be
    overwritten with the rights of the user running the dispatch-conf or
    qpkg, which could be the root user.
  
Workaround :

    There is no known workaround at this time."
