Exposure of Environmental Variables and arbitrary INI file values to an Unauthorized Actor vulnerability in The Document Foundation LibreOffice. URLs could be constructed which expanded environmental variables or INI file values, so potentially sensitive information could be exfiltrated to a remote server on opening a document containing such links. This issue affects LibreOffice: from 24.8 before < 24.8.4.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in The Document Foundation LibreOffice allows Absolute Path Traversal. An attacker can write to arbitrary locations, albeit suffixed with ".ttf", by supplying a file in a format that supports embedded font files. This issue affects LibreOffice: from 24.8 before < 24.8.4.

Certificate Validation user interface in LibreOffice allows potential vulnerability. Signed macros are scripts that have been digitally signed by the developer using a cryptographic signature. When a document with a signed macro is opened a warning is displayed by LibreOffice before the macro is executed. Previously if verification failed the user could fail to understand the failure and choose to enable the macros anyway. This issue affects LibreOffice: from 24.2 before 24.2.5.

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.
