Improper certificate validation vulnerability in LibreOffice - CVE-2021-25633ID: oval:org.secpod.oval:def:76134 | Date: (C)2021-11-18 (M)2023-12-02 |
Class: VULNERABILITY | Family: windows |
The host is installed with LibreOffice 7.0.x before 7.0.6 or 7.1.x before 7.1.2 and is prone to an improper certificate validation vulnerability. A flaw is present in the application, which fails to properly handle digital signatures of ODF documents. Successful exploitation allows attackers to create a digitally signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the document to combine multiple certificate data, which when opened caused LibreOffice to display a validly signed indicator but whose content was unrelated to the signature shown.
