CVE-2020-12802

Name of the Vulnerable Software and Affected Versions LibreOffice versions prior to 6.4.4

Description The issue is related to a flaw in LibreOffice's "stealth mode", which allows only documents from trusted locations to retrieve remote resources. This mode is not enabled by default but can be activated by users to prevent the inclusion of remote resources within a document. The flaw specifically concerns remote graphic links loaded from docx documents, which were not protected prior to version 6.4.4. This could potentially allow a remote attacker to access confidential data due to the lack of protection for internal data.

Recommendations For versions prior to 6.4.4, update to version 6.4.4 or later to resolve the issue. As a temporary workaround, consider disabling the loading of remote graphic links from docx documents until the update is applied. Restrict access to sensitive documents and locations to minimize the risk of exploitation.
