Threats affecting pkg:deb/debian/libreoffice

An out-of-bounds write vulnerability exists in The Document Foundation's LibreOffice when processing crafted OOXML documents with mismatched encryption salt parameters. This affects LibreOffice versions 26.2 before 26.2.3 and 25.8 before 25.8.7. The vulnerability is classified under CWE-787 and has a medium severity with a CVSS 4.0 base score of 5.

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 a link in a browser using that scheme could be constructed with an embedded inner URL that when passed to LibreOffice could call internal macros with arbitrary arguments. This issue affects LibreOffice: from 24.8 before < 24.8.5, from 25.2 before < 25.2.1.

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.
