22 Feb 2022 — LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to create a digitally signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the document to contain both "X509Data" and "KeyValue" children of the "KeyInfo" tag, which when... • https://lists.debian.org/debian-lts-announce/2023/03/msg00022.html • CWE-295: Improper Certificate Validation CWE-347: Improper Verification of Cryptographic Signature •

12 Oct 2021 — LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to modify a digitally signed ODF document to insert an additional signing time timestamp which LibreOffice would incorrectly present as a valid signature signed at the bogus signing time.

03 May 2021 — In the LibreOffice 7-1 series in versions prior to 7.1.2, and in the 7-0 series in versions prior to 7.0.5, the denylist can be circumvented by manipulating the link so it doesn't match the denylist but results in ShellExecute attempting to launch an executable type. En la serie LibreOffice 7-1 en versiones anteriores a 7.1.2, y en la serie 7-0 en versiones anteriores a 7.0.5, la denylist puede ser omitida al manipular el enlace para que no coincida con la denylist pero resulte en ShellExecute intentando in... • https://positive.security/blog/url-open-rce#open-libreoffice • CWE-184: Incomplete List of Disallowed Inputs •

07 Jan 2021 — The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4.

08 Jun 2020 — 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.

https://notcve.org/view.php?id=CVE-2020-12802
08 Jun 2020 — 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.

https://notcve.org/view.php?id=CVE-2020-12801
18 May 2020 — If LibreOffice has an encrypted document open and crashes, that document is auto-saved encrypted. On restart, LibreOffice offers to restore the document and prompts for the password to decrypt it. If the recovery is successful, and if the file format of the recovered document was not LibreOffice's default ODF file format, then affected versions of LibreOffice default that subsequent saves of the document are unencrypted. This may lead to a user accidentally saving a MSOffice file format document unencrypted... • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00011.html • CWE-311: Missing Encryption of Sensitive Data CWE-312: Cleartext Storage of Sensitive Information •

27 Sep 2019 — LibreOffice documents can contain macros. The execution of those macros is controlled by the document security settings, typically execution of macros are blocked by default. A URL decoding flaw existed in how the urls to the macros within the document were processed and categorized, resulting in the possibility to construct a document where macro execution bypassed the security settings. The documents were correctly detected as containing macros, and prompted the user to their existence within the document... • https://packetstorm.news/files/id/156474 • CWE-116: Improper Encoding or Escaping of Output CWE-838: Inappropriate Encoding for Output Context •
