The same flaw was known as the CVE-2021-25635 vulnerability in LibreOffice. The CVE-2021-41832 flaw tracked in the OpenOffice was disclosed by four researchers from the Ruhr University Bochum. Weaknesses have been fixed with the newest versions Attackers can inject other algorithms into these documents and sign them, suggesting that they are not tampered with and signed by a trusted party. If these flaws get successfully used and permit the attacker to timestamp the document, alter the contents, the document can be used as a trustworthy piece. Content manipulation with certificate validation attack. The timestamp manipulation with signature wrapping.
The content and macro manipulation flaw with double certificate attack. Signing the random document and faking its legitimacy is the way to trick users into allowing the macros and running malicious code. These flaws are not high in severity, but the consequences can be serious once the flaw gets exploited and signatures are forged in document macros.

The only way to get rid of the window showing the warning message is to “force-close the entire browser using either the Windows task manager or the Force Close function in macOS,” Ars Technica notes. The number isn’t associated with Microsoft, and victims would likely be asked to pay the person on the other end of the line in order to resolve the fake issue.
