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.
Improper Input Validation vulnerability in GStreamer integration of The Document Foundation LibreOffice allows an attacker to execute arbitrary GStreamer plugins.
In affected versions the filename of the embedded video is not sufficiently escaped when passed to GStreamer enabling an attacker to run arbitrary gstreamer plugins depending on what plugins are installed on the target system.
Insufficient macro permission validation of The Document Foundation LibreOffice allows an attacker to execute built-in macros without warning.
In affected versions LibreOffice supports hyperlinks with macro or similar built-in command targets that can be executed when activated without warning the user.
Improper access control in editor components of The Document Foundation LibreOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of LibreOffice documents that used "floating frames" linked to external files, would load the contents of those frames without prompting the user for permission to do so. This was inconsistent with the treatment of other linked content in LibreOffice. This issue affects: The Document Foundation LibreOffice 7.4 versions prior to 7.4.7; 7.5 versions prior to 7.5.3.
