LibreOffice is a suite that is compatible with other major office softwares and can be executed on a variety of platforms.LibreOffice is vulnerable to a trust management issue. An attacker could exploit the vulnerability by manipulating the documentsignatures.xml or macrosignatures.xml stream in a document to combine multiple certificate data to create a digitally signed ODF document that, when opened, causes LibreOffice to display an indicator of a valid signature, but whose contents are unrelated to the displayed signature.
