QID 670883: EulerOS Security Update for libreoffice (EulerOS-SA-2021-1687)
LibreOffice is an Open Source, community-developed, office productivity suite.It includes the key desktop applications, such as a word processor,spreadsheet, presentation manager, formula editor and drawing program, with a user interface and feature set similar to other office suites. Sophisticated and flexible, LibreOffice also works transparently with a variety of file formats, including Microsoft Office File Formats.
Security Fix(es):
LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to disable LibreOffice's ability to include remote resources within a document. A flaw existed where bullet graphics were omitted from this protection prior to version 6.2.5. This issue affects: Document Foundation LibreOffice versions prior to 6.2.5.(CVE-2019-9849)
ODF documents can contain forms to be filled out by the user. Similar to HTML forms, the contained form data can be submitted to a URI, for example, to an external web server. To create submittable forms, ODF implements the XForms W3C standard, which allows data to be submitted without the need for macros or other active scripting Prior to version 6.4.4 LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction is required to submit the form, but to avoid the possibility of malicious documents engineered to maximize the possibility of inadvertent user submission this feature has now been limited to http[s] URIs, removing the possibility to overwrite local files. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4.(CVE-2020-12803)
Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.
An arbitrary attacker may exploit this vulnerability to compromise the system.
