Libreoffice: >> Libreoffice >> 7.3.3 Security Vulnerabilities
Improper Certificate Validation vulnerability in LibreOffice "LibreOfficeKit" mode disables TLS certification verification
LibreOfficeKit can be used for accessing LibreOffice functionality
through C/C++. Typically this is used by third party components to reuse
LibreOffice as a library to convert, view or otherwise interact with
documents.
LibreOffice internally makes use of "curl" to fetch remote resources such as images hosted on webservers.
In
affected versions of LibreOffice, when used in LibreOfficeKit mode
only, then curl's TLS certification verification was disabled
(CURLOPT_SSL_VERIFYPEER of false)
In the fixed versions curl operates in LibreOfficeKit mode the same as in standard mode with CURLOPT_SSL_VERIFYPEER of true.
This issue affects LibreOffice before version 24.2.4.

Unchecked script execution in Graphic on-click binding in affected LibreOffice versions allows an attacker to create a document which without prompt will execute scripts built-into LibreOffice on clicking a graphic. Such scripts were previously deemed trusted but are now deemed untrusted.

LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint server. An additional scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In the affected versions of LibreOffice links using that scheme could be constructed to call internal macros with arbitrary arguments. Which when clicked on, or activated by document events, could result in arbitrary script execution without warning. This issue affects: The Document Foundation LibreOffice 7.4 versions prior to 7.4.1; 7.3 versions prior to 7.3.6.
