The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2020:4628 advisory.

  - 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 remote     graphic links loaded from docx documents were omitted from this protection prior to version 6.4.4. This     issue affects: The Document Foundation LibreOffice versions prior to 6.4.4. (CVE-2020-12802)

  - 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.

According to the versions of the libreoffice packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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)

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5694-1 advisory.

    It was discovered that LibreOffice incorrectly handled links using the Office URI Schemes. If a user were     tricked into opening a specially crafted document, a remote attacker could use this issue to execute     arbitrary scripts. (CVE-2022-3140)

    Thomas Florian discovered that LibreOffice incorrectly handled crashes when an encrypted document is open.
    If the document is recovered upon restarting LibreOffice, subsequent saves of the document were     unencrypted. This issue only affected Ubuntu 18.04 LTS. (CVE-2020-12801)

    Jens Mller discovered that LibreOffice incorrectly handled certain documents containing forms. If a user     were tricked into opening a specially crafted document, a remote attacker could overwrite arbitrary files     when the form was submitted. This issue only affected Ubuntu 18.04 LTS. (CVE-2020-12803)

    It was discovered that LibreOffice incorrectly validated macro signatures. If a user were tricked into     opening a specially crafted document, a remote attacker could possibly use this issue to execute arbitrary     macros. This issue only affected Ubuntu 18.04 LTS. (CVE-2022-26305)

    It was discovered that Libreoffice incorrectly handled encrypting the master key provided by the user for     storing passwords for web connections. A local attacker could possibly use this issue to obtain access to     passwords stored in the users configuration data. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2022-26306, CVE-2022-26307)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4628 advisory.

    LibreOffice is an open source, community-developed office productivity suite. It includes key desktop     applications, such as a word processor, a spreadsheet, a presentation manager, a formula editor, and a     drawing program. LibreOffice replaces OpenOffice and provides a similar but enhanced and extended office     suite.

    The following packages have been upgraded to a later upstream version: libreoffice (6.3.6.2), libcmis     (0.5.2), liborcus (0.14.1). (BZ#1796893)
