CVE-2018-10583 was assigned for Information disclosure via SMB link
embedded in ODF document

A LibreOffice document with a linked image, which is on a samba share,
will cause LibreOffice to automatically initiate a samba connection to
retrieve the image. This is analogous to how opening HTML documents
which contain links to images on remote web sites are automatically
fetched by web browsers.

If this is combined with an underlying flaw in Microsoft Windows (NTLM
Hash Leaks) then this provides an additional vector by which a windows
user password hash can leak.

Since LibreOffice 5.4.7, and 6.0.4 in the 6.X series, end users or
administrators can disable this functionality to automatically fetch
such linked images via "tools->options->security->options->block any
links from documents not among the trusted locations". By default this
options remains off in those updates.
