Description Wolfgang Frisch 2020-06-10 13:04:19 UTC
CVE-2020-12802

LibreOffice has a 'stealth mode' in which only documents from locations deemed
'trusted' are allowed to retrieve remote resources. This mode is not the default
mode, but can be enabled by users who want to disable LibreOffice's ability to
include remote resources within a document. A flaw existed where remote graphic
links loaded from docx documents were omitted from this protection prior to
version 6.4.4. This issue affects: The Document Foundation LibreOffice versions
prior to 6.4.4.
